Our usage of inodes is dual: - the Index.db and Data.db components are pinned in memory as the files are open - all other components are read once and never looked at again As such, tune the kernel to prefer evicting dcache/inodes to memory pages. The default is 100, so the value of 2000 increases it by a factor of 20. Ref https://github.com/scylladb/scylladb/issues/14506 Closes #14509
