free memory in Linux
I'm trying to determine if my server needs more memory.
free -m total used free shared buffers cached Mem: 7993 7719 274 0 372 5866 -/+ buffers/cache: 1480 6513 Swap: 11617 0 11616
The cached is high and free is low (the server handles a lot of requests). Is this indicative that the server could benefit from additional memory since all free memory is being used as cache?
