There's no 10% speedup - they straight up lie here. XMRig 5.2.0 gives the same or better hashrate on properly tuned Linux and even Windows (see https://www.reddit.com/r/MoneroMining/comments/e9tuvd/randomx_boost_guide_for_ryzen_on_windows_9100_hs/). Basically, set up large/huge pages, MSR mod, no programs running in the background, and you're good without using some closed source ecosystem.
