How do I enable HugePages?
Execute ‘sysctl -p’ command to enable the hugepages parameter. Note : It’s recommended to restart the system after configuring hugepages as the chances of having free contiguous memory (for hugepages allocation) is much greater when a system is started.
What is large pages in Windows?
Large-page support enables server applications to establish large-page memory regions, which is particularly useful on 64-bit Windows. Each large-page translation uses a single translation buffer inside the CPU.
What are huge pages mining?
Computer memory is divided into page blocks, and in most operating systems pages larger than 4 KB are called HugePages. HugePages, also known as LargePages (on Windows) and SuperPages (on macOS), are an essential element for mining algorithms on the main processor of a computer.
What is the difference between HugePages and transparent huge pages?
Transparent Hugepages are similar to standard HugePages. However, while standard HugePages allocate memory at startup, Transparent Hugepages memory uses the khugepaged thread in the kernel to allocate memory dynamically during runtime, using swappable HugePages.
How do I increase virtual memory in Windows 10?
Go to the Start Menu and click on Settings. Type performance. Choose Adjust the appearance and performance of Windows. In the new window, go to the Advanced tab and under the Virtual memory section, click on Change.
What is large page memory?
Large memory pages are pages of memory which are significantly larger than 4 kb, usually 2 Mb.
Why Gpedit MSC is not working?
If you find the Group Policy Editor (gpedit. msc) missing in Windows 10, you should first try to enable or open gpedit: press Windows + R to open Run dialog -> type gpedit. … Upgrade to Windows 10 Pro or Enterprise. Copy & paste GroupPolicy, GroupPolicyUsers, and gpedit.
What is lock pages in memory?
Lock Pages in Memory is a Windows policy that determines which accounts can use a process to keep data in physical memory, preventing the system from paging the data to virtual memory on disk. Locking pages in memory may keep the server responsive when paging memory to disk occurs.
How do I access local security policy?
To open Local Security Policy, on the Start screen, type secpol. msc, and then press ENTER. Under Security Settings of the console tree, do one of the following: Click Account Policies to edit the Password Policy or Account Lockout Policy.
What is the use of huge pages in Linux?
HugePages is a feature integrated into the Linux kernel 2.6. Enabling HugePages makes it possible for the operating system to support memory pages greater than the default (usually 4 KB).
How do I activate huge pages on XMRig?
1GB huge pages Linux only
By default this feature disabled, to enable use option «1gb-pages»: true, in «randomx» object. If use XMRig with root privileges, additional system configuration not required. As an alternative you can go to miner source directory and run sudo ./scripts/enable_1gb_pages.sh script source .
How do I know if XMRig is working?
Windows users can double click on xmrig.exe. Users of other operating systems should cd into the directory that contains XMRig and then type ./xmrig and press return. If you see green messages saying that shares have been accepted, congratulations, everything is working!
The benefit of using large pages
CPUs have a virtual memory space that is decoupled from the actual physical memory, in blocks called pages. Usually these are 4KB (4096 bytes) in size, and so there are a lot of pages used in rendering large images.
Because the IFS process leads to very incoherent memory access patterns, the CPU cache for page mappings (the TLB) can thrash pretty hard. By using large pages, which are typically 2MB in size, these cache misses are much less frequent, leading to substantially improved performance. 10-20% overall rendering speed improvement on an i7 CPU is common, and the speedup increases at higher resolution.
Here’s an example from a 4K (3840×2160) AA 2 animation frame, showing a 12% speedup:
Without large pages.

How to enable large page support on Windows
Programs can be given permissions to lock pages in memory in the Local Security Policy settings; Windows Home or starter versions don’t include an interface for this, however there are guides for this as well.
This section assumes you’re using Windows Professional, Enterprise, Ultimate or Server:
- From the Start menu, open Local Security Policy (under Administrative Tools).
- Under Local Policies\User Rights Assignment, double click the Lock Pages in Memory setting.
- Click Add User or Group and type your Windows user name.
- Either log off and then log back in or restart your computer — unfortunately it won’t work without this step.
Editing your shortcut to run as Administrator
Programs furthermore need to be run with Admin privileges in order to use large page allocations. To avoid having to right-click and select Run as Administrator every time, you can edit your shortcut to do this automatically, in the «Compatibility» section:
Troubleshooting
You can verify that large page support is enabled by opening the About dialog, which will say «Large page support enabled» if it could successfully get the permissions for large page allocations.
The 12.2 documentation says “Large page usage locks the entire SGA into physical memory“. However, this is not always true.
Consider the case of mixed mode, (ORA_SID_LPENABLE=2), with fragmented memory. Some of the SGA has to be allocated with normal pages. The alert log will show:
Fri Jul 14 13:01:56 2017 Large page enabled. Mode is : 2 Fri Jul 14 13:01:56 2017 Large page size : 2097152 Large page request size : 16777216 Fri Jul 14 13:01:56 2017 Large page Mixed-mode : Max time for each Large page allocation can be : 30000 msecs Fri Jul 14 13:01:56 2017 Allocated Large Pages memory of size : 14680064 Fri Jul 14 13:01:56 2017 Allocated Large Pages memory of size : 1073741824 Fri Jul 14 13:01:56 2017 Allocated Large Pages memory of size : 536870912 Fri Jul 14 13:01:56 2017 Allocated Large Pages memory of size : 134217728 Fri Jul 14 13:01:57 2017 Allocated Large Pages memory of size : 50331648 Fri Jul 14 13:01:57 2017 Allocated Large Pages memory of size : 33554432 Fri Jul 14 13:01:57 2017 Large page Mixed-Mode : Failed to allocate memory in Large Pages. Allocation will be in normal pages
The normal sized pages of the SGA are not locked into memory, (and can’t be with LOCK_SGA), which could impact performance.
From x$ksmge and x$kmgsct

We can see large page usage, but the entire SGA is not locked in RAM. (Part of the shared pool is not locked).
Unfortunately, we can’t use the LOCK_SGA parameter to fix this because the instance will fail to start with that parameter set when large pages are used.
The DBA’s Options
- Use normal pages and set LOCK_SGA=true
Incurs the overhead of using 4KB pages on large memory systems. - Use ORA_SID_LPENABLE=1 and set LOCK_SGA=false
Benefits from large pages, but the instance may fail to start if the server hasn’t been rebooted. Not ideal for a large production server with multiple databases on it. - Use ORA_SID_LPENABLE=2 and set LOCK_SGA=false
Benefits from large pages, but unless the instance is restarted soon after a reboot each time, part of the SGA will often comprise normal pages, which are not locked, and so could be paged out.
While I appreciate the value of consistent performance, I still favour option 3 for large memory systems. Even if reboots aren’t possible before each instance is started, the instance will not fail to start and most of the SGA should be in large locked pages. To mitigate the risk of some of the SGA being paged out, I’d reserve a lot of RAM to handle spikes in demand from other processes, such as Windows Update.
Making the Oracle World a Better Place
Medium Term
I have filed a bug with Oracle Support to correct the documentation.
Update – the 19c documentation includes this note:
In regular mode, large page usage locks the entire SGA into physical memory. Physical memory is not released during a shrink operation. In mixed mode, only the large pages from the SGA are locked in physical memory, not released during a shrink operation and regular pages remain pageable.
Long Term
Surely the Oracle code could be altered to behave as if LOCK_SGA=true when mixed mode wasn’t able to allocate large pages for the entire SGA. Having the entire SGA locked in RAM, with as many large pages as possible, would be the ideal situation, so I have logged an enhancement request:
Bug 26670992 – BOTH NORMAL AND LARGE PAGES USED BY SGA SHOULD BE LOCKED WHEN IN MIXED MODE
By Franck Pachot
.
In a previous post about enabling large page on Windows Server, I explained that it’s possible to use large pages with Automatic Memory Management (AMM, where sizing if SGA and PGA is automatic with MEMORY_TARGET setting) but possible does not mean that it is recommended. We feel that it’s not a good idea, but are there reasons for it or it’s just our Linux background that brings this opinion?
SGA_MAX_SIZE=4G, MEMORY_MAX_SIZE=6G
What is the size of allocated large pages? If it is set, SGA_MAX_SIZE is the size allocated as large pages when ORA_LPENABLE=1, even if you’ve set some MEMORY_MAX_SIZE:
I take screenshots with all information: the init.ora settings and the regedit entry on top-left. Latest sqlplus commands on top right (here screenshot is just after the startup). And memory given by Sysinternals RamMap.
So, when SGA_MAX_SIZE is set, it’s the maximum size of SGA that can be allocated, and this is what is allocated at startup from physical memory until the end of the instance. You can reduce the SGA_TARGET dynamically, but I don’t see any reason for that as the memory allocated in large page will not be released, nor swapped, nor usable for PGA.
SGA_MAX_SIZE unset, MEMORY_MAX_SIZE=6G
If we don’t set SGA_MAX_SIZE, then the SGA can grow up to MEMORY_MAX_SIZE and this is what is allocated at startup when ORA_LPENABLE=1:
Physical memory must be free
When ORA_LPENABLE=1 and not enough memory is available if physical memory, you get an error (ORA-27102 OS 1450) at startup:
What I did here was running 10 instances of SQLDeveloper to use 2GB on my 8GB VM.
Fragmentation
Not only we need the SGA to be allocated from physical memory, but it needs to be contiguous. Here is a screenshot I took some times later with those sqldev closed but after I had lot of activity on the VM:
As you see here, there is enough RAM (7GB) but not contiguous.
The recommandation when using large pages on Windows is to start all instances immediately after server restart, and if you have to restart an instance you may have to reboot the server. Note that the major advantage of large pages is on virtualized environments, and then you should not have more that one instance in a server. If you are convinced that with Windows it’s always good to restart the server, here you have a reason: fragmentation breaks large pages.
Mixed-mode
Let’s go back to the state where I had 10 SQLDeveloper opened. I change ORA_LPENABLE to 2 instead of 1 to be able to start the instance even is there is not enough contiguous RAM for the SGA (here for the MEMORY_TARGET as no SGA_MAX_SIZE is defined).
Now, I’m able to start the instance (but it took several minutes here as physical memory is exhausted):
Instance is started, but not all 6GB have been allocated as large pages. In this case where SGA_TARGET is 3GB, I presume that all SGA uses large pages unless we increase SGA_TARGET higher than the 5GB allocated, but this is only my guess.
MEMORY_MAX_SIZE and ORA_LPENABLE=0
So, now that we know how it works, let’s see the danger to run AMM with large pages.
Here is a database in AMM where MEMORY_TARGET=5GB after running some query that needs several GB of buffer cache (thanks to CACHE hint and “_serial_direct_read”=never) and several GB of PGA (thanks to manual workarea size policy). First, without large pages:
The RAM allocation is all private process memory (on Windows, Oracle processes are actually threads from one process only). And AMM achieves its goal: target is MEMORY_TARGET=5GB and this is what we have allocated for the instance.
MEMORY_MAX_SIZE and ORA_LPENABLE=2
Now doing the same with large page:
MEMORY_MAX_SIZE is supposed to be used for PGA+SGA and a large use of PGA should reduce SGA. But it cannot be done here because SGA is large page and PGA cannot be allocated from large pages. This means that AMM with large page do not achieve its goal. MEMORY_MAX_SIZE acts like having set SGA_MAX_SIZE to that value and very small PGA_AGGREGATE_TARGET. In this example (artificial example as I used manual workarea size policy, but same happens with auto and several sessions) physical memory is exhausted.
From that, I think we have a reason to recommend ASSM (Automatic Shared Memory Management) with large pages, as with Linux. In Oracle, because of the threaded architecture, it’s not a requirement but in my opinion it’s still a good idea to differentiate those memory areas that are so different:
- SGA: one area allocated at startup, preferentially from large pages
- PGA: variable size areas allocated and de-allocated by sessions
If you have more than few GB on your server, you should size SGA and PGA independently and benefit from large pages for SGA. Do not set MEMORY_MAX_SIZE then. Don’t set MEMORY_TARGET either as it acts as MEMORY_MAX_SIZE if this one is not set.
Added 18th December 2016
In the above, I explained that using AMM is not a good idea with large pages because the allocated MEMORY_TARGET was not used for PGA. It can be worse. AMM may try to release some large pages to allocate small pages for PGA. And re-get large page later. This can bring huge fragmentation and contention. This has been confirmed by Oracle developers.
So the conclusion is clear: don’t use AMM with large pages even on Windows where it is allowed. Recommandation is to use large pages and set SGA_TARGET and PGA_AGGREGATE_TARGET without setting MEMORY_TARGET.

Configuring Huge Paging File Size
A. Understanding the role of the paging file in huge pages
In order to optimize the performance of huge pages on Windows 10, it is essential to configure the appropriate paging file size. The paging file, also known as the page file or swap file, is a system file that temporarily stores data when the physical memory (RAM) is full. By default, Windows automatically manages the paging file size, but for optimal performance with huge pages, manual configuration is recommended.
When using huge pages, the size of the paging file directly affects the overall system performance. It is important to allocate enough space in the paging file to support the increased memory requirements of huge pages. Insufficient paging file size may lead to performance issues and potential crashes, as the system may run out of virtual memory.

Allocating Memory for Huge Pages
A. Determining the amount of memory to allocate for huge pages
Allocating memory for huge pages is an important step in maximizing the performance gains of enabling huge pages on Windows 10. To determine the amount of memory to allocate for huge pages, you need to consider the total amount of available RAM on your system.
First, you need to check the size of your huge pages. As mentioned earlier, huge pages have a larger page size compared to standard pages, which results in reduced translation lookaside buffer (TLB) overhead and improved performance. Depending on your specific requirements and the applications you use, you may want to allocate more memory for huge pages.
To calculate the amount of memory to allocate, divide the total available memory by the size of each huge page. For example, if you have 16GB of RAM and each huge page size is 2MB, you would divide 16,000MB by 2MB to get 8,000 huge pages.
B. Adjusting the huge page size based on memory allocation
After determining the amount of memory to allocate for huge pages, you may need to adjust the huge page size to ensure optimal memory utilization. Windows 10 supports different huge page sizes, including 2MB, 4MB, and 1GB.
If you have a large memory allocation for huge pages, it is generally recommended to use larger page sizes, such as 1GB, as they result in fewer entries in the page table and TLB. On the other hand, if you have a smaller memory allocation, choosing smaller page sizes like 2MB or 4MB can help avoid potential memory wastage.
To adjust the huge page size, you will need to modify the Windows registry key for huge pages, as discussed in Section IBy changing the appropriate registry value, you can select the desired page size for optimal memory allocation.
C. Modifying memory allocation settings in BIOS
In addition to adjusting the huge page size in the Windows registry, you may also need to modify memory allocation settings in the Basic Input/Output System (BIOS) of your system. Some systems have BIOS options that allow you to allocate a specific portion of memory for use as huge pages.
To modify memory allocation settings in the BIOS, restart your system and enter the BIOS settings menu. Look for options related to memory allocation or memory management. Depending on your system manufacturer and BIOS version, the specific options may vary. Enable the option to allocate memory for huge pages and specify the amount of memory to allocate based on your calculations from earlier.
Once you have made the necessary changes in the BIOS, save the settings and exit. Your system will now allocate the specified amount of memory for huge pages, resulting in improved performance for resource-intensive applications.
By properly allocating memory for huge pages and adjusting the page size based on your memory allocation, you can optimize the performance benefits of enabling huge pages on Windows 10. This step is crucial in ensuring that your system utilizes the available resources efficiently and provides the desired performance improvements.
A. Tools to measure performance improvement with huge pages
