cache in RAM / linux kernel
Hey.
Question to any Linux kernel hacker out there, before I go and bug
linux-kernel. I have a pretty low-RAM box and I notice that with 2.2
about one-third of the RAM is used for caching, even though swap is
excessively used making speed very low. It has 32 MB of RAM, and many
users run stuff on it -- look at the free output:
total used free shared buffers cached
Mem: 31200 30420 780 16884 652 11800
-/+ buffers/cache: 17968 13232
Swap: 66376 32768 33608
My question -- is the parameter tunable (i.e. can I tell the kernel
how much RAM to use for cache)? Where can I find it?
