Hi,
I am using FC2-Linux-2.6.10 Kernel in
dual P4 Xeon Processer
3 GB Physical RAM
2 * 12 GB disked Cache_dir with different SCSI harddisk.
OS File Systen - reiserfs
Squid- 2.6.STABLE2 with
cache_replacement_policy heap LFUDA
memory_replacement_policy heap LFUDA
Server is configured with in bridge mode and tproxy.
Usually when there is 5 MB of traffic squid will use 80 to 90% of CPU
(System load will be 2), after enabling the epoll it come down to 10
to 15% of CPU (System load will be 0.2).
Then i added 5 more MB of traffic the CPU went to 40 to 50% (System
load went to 3). What could be the problem as CPU usage and system
load went high dramatically
sounds to me that you are having lots of disk I/O.
You could use 'top' and watch for processes with 'D' state (column
'S'). iostat / vmstat / sar may confirm that you are having disk I/O.
HTH,
