the tests below are for requesting small pages (<50 bytes) when I ran the same tests with 100K pages the throughput dropped down 3.0 90 requests/sec 3.1 60 requests/sec so, at 6K requests/min (100 requests/sec), you could legitimatly have the system maxed out (depending on your mixture of re

When squid is stop... cpu usage dont go over 5%. Maybe my conf is problem, but I think it is not... I have about 6k request per minute so I am confused with this poor performance. About 1k users access squid in peek with about 80Mbps traffic. On Sat, 26 Mar 2011 14:06:10 -0700 (PDT), da...@lang

In my testing in the last couple of weeks, I've found that newer squid versions take significantly more cpu than the older versions, translating into significantly less capacity I didn't test 2.7, but in my tests 3.0 4200 requests/sec 3.1.11 2100 requests/sec 3.2.0.5 1400 requests/sec (able to

With squid 3.1.11 CPU usage of squid process is 100% during 10am to 10 pm... I will try now with 2.7.Stable9. I just dont know what could be the problem. On 23.3.11. 16.24, Marcus Kool wrote: Zivanic Dejan wrote: On 3/23/11 3:27 AM, Marcus Kool wrote: Dejan, Squid is known to be CPU boun

Dejan, Squid is known to be CPU bound under heavy load and the Quad core running at 1.6 GHz in not the fastest. A 3.2 GHz dual core will give you double speed. The config parameter "minimum_object_size 10 KB" prevents that objects smaller than 10 KB are not written to disk. I am curious to know
