Aggressive swapping even with vm.swappiness=1 with MGLRU ======================================================== Reading a large mmapped file leads to a super agressive swapping. Reducing vm.swappiness even to 1 does not have effect. Demo: https://www.youtube.com/watch?v=J81kwJeuW58 Linux 5.17-rc3, Multigenerational LRU v7, vm.swappiness=1, MemTotal: 11.5 GiB. $ cache-bench -r 35000 -m1 -b1 -p1 -f test20000 Reading mmapped file (file size: 20000 MiB) cache-bench v0.2.0: https://github.com/hakavlad/cache-bench Swapping started with MemAvailable=71%. At the end 33 GiB was swapped out when MemAvailable=60%. Is it OK?
