Re: what is sufficient free memory?

["Erik Peter P. Abella" <beyonder@centinet.com>]

Hello All,


Thanks for all the reponses. From most of the replies, can I gather that
I'll have to observe my how much is being swapped to determine whether I
should immediately "up" the RAM back to 128MB? (and pester the tight-wad
suits who'll approve the requesition)

To paint a better picture, here's an entire top screen:

70 processes: 69 sleeping, 1 running, 0 zombie, 0 stopped
CPU states:  0.1% user,  0.7% system,  0.0% nice, 99.0% idle
Mem:   63124K av,  60764K used,   2360K free,  38700K shrd,  32216K buff
Swap: 104380K av,   3572K used, 100808K free                  7772K

The stats on the swapping have been constant for the past hour or so,
but notable too is that it's 4am here in the Philippines and there
aren't any subscribers who've dialed in and engaged squid as they surf.
I guess I'll be able to get a better idea later on when my subscribers
start pouring in.

Mabuhay kayong lahat at debian!
(long live you all and debian)
