Jádro 6.17 je v průměru asi o 37 % rychlejší než jádro 5.15 Server Phoronix dnes testoval jaký má na výkon vliv verze jádra. V současnosti lze stále používat aktualizovaná LTS jádra od verze 5.4. Tak daleko experiment nešel a testoval od 5.15, které vyšlo v roce 2021, tedy před čtyřmi lety. K tomu byl zvolen HW z té doby: duální AMD EPYC 7773X. Jádro bude mít rychlejší swap V současnosti má linuxové jádro velmi jednoduchý algoritmus obsluhy swapu. Ten má tu výhodu, že spotřebuje jen minimum paměti. Výkon však není optimální. O zlepšení algoritmu se mluvilo na konferenci Linux Storage, Filesystem, MM & BPF. Open Source Summit Europe V Amsterdamu probíhá Open Source Summit Europe.
