[users@httpd] Apache benchmark result analysis

[Austin Einter <au...@gmail.com>]

Dear All
I have setup a site www.netcloudjobs.com using Apache 2.2.15.

I found my site is slow. Due to some reasons I am not using APC/Varnish
cache. I am using only Memcache.

MySql 5.5 (Innodb) is used.


My server is centos 6.3 , I7, 16GB RAM.

When I executed apache benchmark command, I found below result. Can
somebody kindly tell if this looks OK or My Webserver needs to be optimized.

[root@ip-173-201-189-43 mysql]# ab -n 2000 -c 10 http://localhost/
