Hi, I'm using 2.5.STABLE8 from Debian Sarge and experiencing very high utilization and random stalls client side at peek time. Did upgrade to 2.5.STABLE9 from Debian Unstable, but no difference so far. I'm almost sure I misconfigured some (or all ;-)) things, but totally out of options. To see some performance: http://rosink.op.het.net/squid/day_stats.png http://rosink.op.het.net/squid/week_stats.png http://rosink.op.het.net/squid/info.txt Box is a Xeon 2.4Ghz with 1GB ram and three dedicated 9GB SCSI cache volumes. Connections are coming from several (50 max) child proxies, mostly BorderManager and ISA, used by about 2500 workstations. I'm using the following configuration: http://rosink.op.het.net/squid/squid.conf I'm aware of the extreme number of squidguard redirectors (32), but that's the only way to make the log messages about blocking redirectors disappear. Could anyone see what's happening ? Thanks, Jorgen Rosink
