Enabling MGLRU could give some performance benefits. Right now it is compiled into the kernel but not enabled by default

Do you have any specific usecase in mind or is this more of a "I want to play with this new reclaim implementation"?

No specific use case but others might find this useful due to the performance benefits. Arch enabled it already and I presume Fedora will have it enabled when 6.1 reaches Fedora 37

The MGLRU can be enabled by echo y >/sys/kernel/mm/lru_gen/enabled more on that in Documentation/admin-guide/mm/multigen_lru.rst in the kernel source tree. I would recommend enabling that and reporting back any noticeable improvements. I would much rather enable MGLRU based on actual numbers. -- You are receiving this mail because: You are on the CC list for the bug.
