Basically I have a server failing under load. Its a editorial news site that see irregular traffic spikes. I'm tearing my hair out trying to stabilise the LAMP configuration.
Current Time: Wednesday, 14-Dec-2011 15:13:06 SAST Restart Time: Wednesday, 14-Dec-2011 14:08:44 SAST Parent Server Generation: 0 Server uptime: 1 hour 4 minutes 21 seconds Total accesses: 52825 - Total Traffic: 530.2 MB CPU Usage: u281.32 s20.44 cu0 cs0 - 7.82% CPU load 13.7 requests/sec - 140.6 kB/second - 10.3 kB/request 19 requests currently being processed, 13 idle workers
Am I crazy or should my dedicated server be making easy meat of this load?
- Intel i7
- 8GB DDR3
- Soft raid 1
Load averages typically around 3 but twice today it climbed to 30+; dumped its clients and stabilised back to 2.
``top'' reveals little of interest with mysql sitting at 11% cpu.
In your opinion is this possibly a hardware issue? I see the raid maybe clogging up with a unresponsive ata interface in one such case of bad load?
How many req/s would you say is fair for a box this size?
