Is there a way to modify Debian settings so the memory could be used more for disk read/write caching ? I am already using RAID 0 but thats not enough for multiple users, and the disk is almost struggled.
Torrents use the disk very much and rTorrent doesn't have cache settings.
Update: the output of free -m is
total used free shared buffers cached Mem: 7899 7848 50 0 59 7369 -/+ buffers/cache: 420 7479 Swap: 3998 0 3998
Why is so much memory cached ?
