[2]$ cat /proc/meminfo
MemTotal: 7128956 kB
MemFree: 2132556 kB
Buffers: 556832 kB
Cached: 2821408 kB
A supplementary question, can anyone explain what "buffers" and "cached"
are? I have a performance problem with postgresql (discussion is on the
postgresql list), and I see those figures displayed by commands such as
free, top and procinfo but the man pages don't define them.
Buffers = disk buffers (buffers of stuff to be read/written)
Cached = page cache which stores filesystem and process pages...copy of
files in memory
