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, -- Gonzalo A. Arana -- Gonzalo A. Arana
