All, During the normal work out at my company, the squid proxy is reasonably responsive, and seems to work well. However, after roughly 5pm each day, through the night and all during the weekend, web browsing is very slow, with pages taking a very long time (30+ seconds, to sometimes minutes) to load. Does anyone have some suggestions on where I might start looking at this problem? I haven't found anything in the logs that I can detect as relevant. Stopping and starting squid makes no difference. This is a snapshot of top from just a few moments ago, and I'm experiencing the problem at the moment (I'm VPNed in from home, looking at some issues): last pid: 33578; load averages: 0.31, 0.35, 0.18 up 489+09:46:35 16:49:12 45 processes: 1 running, 44 sleeping CPU states: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle Mem: 296M Active, 723M Inact, 167M Wired, 70M Cache, 112M Buf, 743M Free Swap: 1024M Total, 72K Used, 1024M Free PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 33576 root 1 44 0 3488K 1584K CPU1 1 0:00 0.10% top 42017 root 1 44 0 3156K 984K select 1 246:01 0.00% syslogd 1524 root 1 44 0 4628K 1584K select 0 17:29 0.00% ntpd 1065 root 1 8 0 3184K 940K nanslp 0 3:51 0.00% cron 25039 root 1 4 0 3292K 1072K kqread 1 3:22 0.00% master 25041 postfix 1 4 0 3292K 1212K kqread 0 0:43 0.00% qmgr 1814 squid 1 4 0 3104K 928K accept 1 0:01 0.00% frox 33389 kbuff 1 44 0 8384K 3052K select 0 0:00 0.00% sshd 33386 root 1 4 0 8384K 3032K sbwait 1 0:00 0.00% sshd 1058 root 1 44 0 5616K 1884K select 1 0:00 0.00% sshd 68062 root 1 44 0 3472K 1604K select 1 0:00 0.00% bsnmpd 33396 root 1 20 0 4452K 2156K pause 0 0:00 0.00% csh 33252 postfix 1 4 0 3292K 1260K kqread 0 0:00 0.00% pickup 33578 squid 1 44 0 4328K 1668K select 1 0:00 0.00% pinger 33577 squid 1 -8 0 4292K 1396K piperd 0 0:00 0.00% unlinkd 33392 kbuff 1 8 0 3592K 1388K wait 1 0:00 0.00% su 33391 kbuff 1 8 0 3456K 1300K wait 1 0:00 0.00% sh 1107 root 1 5 0 3156K 816K ttyin 0 0:00 0.00% getty 866 root 1 62 0 1888K 420K select 1 0:00 0.00% devd 1112 root 1 5 0 3156K 816K ttyin 0 0:00 0.00% getty 1110 root 1 5 0 3156K 816K ttyin 0 0:00 0.00% getty 1113 root 1 5 0 3156K 816K ttyin 0 0:00 0.00% getty 1111 root 1 5 0 3156K 816K ttyin 1 0:00 0.00% getty 1114 root 1 5 0 3156K 816K ttyin 1 0:00 0.00% getty 1109 root 1 5 0 3156K 816K ttyin 0 0:00 0.00% getty 11008 root 1 5 0 3156K 796K ttyin 1 0:00 0.00% getty 33573 squid 1 8 0 7464K 4048K wait 0 0:00 0.00% squid 136 root 1 20 0 1356K 648K pause 0 0:00 0.00% adjkerntz 33575 squid 17 113 0 358M 268M ucond 0 0:00 0.00% squid Thanks, Kurt
