Average speed increase is negative

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi folks,
i'm running squid for about 30 users with a very close to standard setup.
The proxy is transparrent to the users. I increased the cache size to 14 G
and have allocated about 512 mb ram. Apart from that the conf is standard.

Below I enclose a "calamaris statistic report", which is where my trouble
begins. I often have a negative average speed increase, and my byte hit
ratio is bad - approxematly 3-5 % allthough I get a good request hit
ratio.

My hope is that anyone by looking at the report can help me improve the
overall proxy performance. If needed I'll enclose the squid.conf file.
