Is there a kernel parameter or something I can tune to limit the amount of memory that will be used for cache (i.e. 144 in this example)? Let's say I never wanted that to go past 64.
free -m
total used free shared buffers cached
Mem: 503 399 104 0 67 144
-/+ buffers/cache: 187 315
Swap: 511 0 511
free -m
total used free shared buffers cached
Mem: 503 399 104 0 67 144
-/+ buffers/cache: 187 315
Swap: 511 0 511
