Huge Pages, also known as Large Pages (on Windows) and Super Pages (on BSD) is very important thing for almost all supported CPU mineable algorithms, typical hashrate increase is 20-30% when huge pages used, for RandomX it can increase performance up to 50%. XMRig use term huge pages on all platforms, please don't confusing.
If XMRig use huge pages you will see lines with text like bellow in miner log.
huge pages 100%
For RandomX dataset since version 5.2.0 the miner support 1GB huge pages (regular huge pages size is 2MB), this feature available only on Linux. It increases the hashrate by 1-3% (depends of CPU) and increases memory requirements to 3GB (3 pages) per NUMA node.
By default this feature disabled, to enable use option
"1gb-pages": true, in
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 .
