No matter what I do to the tunable system parameters in /proc (below) I can't get the amount of memory taken by the inode cache to reduce and become freed for userspace programs. /proc/sys/vm/vm_mapped_ratio ( tried 20 - 100 ) /proc/sys/vm/vm_vfs_scan_ratio ( tried 2 - 6 ) How often does the dcache/icache shrinking take place in 2.4? On vfat/fat32, ext2/3 filesystems I don't see anywhere near the amount of lost memory than when using the NTFS filesystem. This is what led me to think that the NTFS driver was leaking, rather than this being an inode cache problem.
