Two dedicated separate servers running with identical configuration of hardware (Dual E5-2620 32GB) in similar environment (CentOS 6.3, Apache+PHP+MySQL) serving similar tasks, but behaving in different way of processing Apache web server - CPU usage 17x times bigger in server which has lower requests.
CPU Usage: u2.03 s1.05 cu316.97 cs0 - 4.35% CPU load 11.9 requests/sec - 5.3 kB/second - 458 B/request
CPU Usage: u16.98 s5.11 cu705.75 cs0 - .243% CPU load 25.4 requests/sec - 13.4 kB/second - 540 B/request
My question: which parameter/s might be responsible for this condition?
