I'm running squid (squid-2.6.STABLE6-4.el5) on an old IBM x330 server (2x 1266MHZ PIII, 1GB RAM, 2 mirrored 36GB disks for OS and 20GB squid-spool), serving set-top-boxes' access to the internet.
We have a feel for the proxy maybe being slow, but can't really pinpoint what the problem might be. Could somebody please have a look at the below numbers to see if something stands out as a potential performance problem ? Some stats from calamaris for the last 24 hours: Proxy statistics ----------------- Total amount: requests 2818623 unique hosts/users: hosts 3427 Total Bandwidth: Byte 15607M Max. Bandwidth usage: MBit/sec 4.42 Proxy efficiency (HIT [kB/sec] / DIRECT [kB/sec]): factor 10.45 Average speed increase: % 100.25 TCP response time of 100%% requests: msec 130 Cache statistics ---------------- Total amount cached: requests 2088373 Request hit rate: % 74.09 Bandwidth savings: Byte 8640M Bandwidth savings in Percent (Byte hit rate): % 55.36 Average cached object size: Byte 4338 Average direct object size: Byte 10004 Average object size: Byte 5806 Incoming request peak --------------------- 429/second 6439/minute 238080/hour TCP-Request duration distribution ----------------------------------------- msec hits byte <= 10 48% 23% <= 100 85% 60% <= 1000 99% 86% File descriptors in use by squid are normally between 50-150, with peaks of 200-1000 once a week. CPU-usage is seldom above 10%, with 1-2% iowait and less than 1% system cpu. -jf
