hi all,

Im new in this forum, and want to ask something about squid perfomance,
just want to ask, i look into my cachemgr.cgi, and it told me:

Memory usage for squid via mallinfo():
        Total space in arena:  111536 KB
        Ordinary blocks:       111320 KB     36 blks
        Small blocks:               0 KB      0 blks
        Holding blocks:          1844 KB      4 blks
        Free Small blocks:          0 KB
        Free Ordinary blocks:     215 KB
        Total in use:          113164 KB 100%
        Total free:               215 KB 0%
        Total size:            113380 KB

Im running squid 2.5Stable 9,
My box is p4 2.8ghz, 2gb ecc ram, 80gb sata hardisk

Is there something wrong with my Total Free Mem= 0% ? or i pushed my box
to far?

NB:
I looked from the running proccess through top, it show:

[root@gx ~]# top
top - 19:18:50 up 16 days, 28 min,  1 user,  load average: 0.10, 0.05, 0.01

    2 root      34  19     0    0    0 S  0.0  0.0   0:01.50 ksoftirqd/0


and when i look deeply, the Free Mem is reduced very fast.....and the
squid process grew quickly instead.

Someone can help me to understand this?

Thank you in Advance,
