Hey , guys, Recently I did some interesting performance testing . I used memory only for the squid configuration . when I set the the cache_mem to following value , I got incresed CPU utilization . cache_mem 4096 MB, cpu :73% (the value from top or squidclient mgr:info) cache_mem 6144 MB , cpu : 85 % cache_mem 8192 MB , cpu : 97.5% I am really wondering why CPU utiliztion get such increse .... I used the same traffic load for the testing . Following is my testing configuration . 1. Hardware configuration (1) Squid Server CPU: 2 AMD 64 bits 2.4GHz CPUs, eachCPU has 2 Cores Memory size: 16G, (2) Client and Web Server : Web Polygraph 3.1.5 2. Squid version :squid-2.6.STABLE19<http://www.squid-cache.org/Versions/v2/2.6/squid-2.6.STABLE19-RELEASENOTES.html> Configuration: ./configure --enable-dlmalloc ...etc... one Squid instance is running on the cache server , squid .conf : cache_mem 8192 MB maximum_object_size_in_memory 2048 KB memory_replacement_policy heap GDSF cache_dir null /tmp memory_pools on memory_pools_limit 256 MB Best Regards -Arkin
