For some reason my squid cache is running at 99% load.
I don't see any abnormal pattern in traffic and number of connections.
Agv. traffic is around 2M/sec and goes upto 3.5M/sec during peak hours.
Max File descriptor open is around 2K.
I'm running squid-2.5.stable4 on FreeBSD-4.9.
The hardware is Dell Power edge with 2.6 Gig P4 HT processor and 2 GB RAM.
I've got custom kernel running with HT enabled. I've got 2 cache dirs (10 Gb
each) on 20 GB SCSI drive dedicated for cache only. This system has been
running since last 30 days. Under same traffic load (and connections) the
avg. cpu usage was around 30% during peak hours. but since last 2 days it is
running at 99% most of the time
I compiled squid with following options:
And these are few lines from my squid.conf:
cache_mem 128 MB
maximum_object_size 32768 KB
maximum_object_size_in_memory 16 KB
tcp_recv_bufsize 65535 bytes
cache_dir aufs /usr/local/squid/cache1 8000 32 512
cache_dir aufs /usr/local/squid/cache2 8000 32 512
I think I need to tweak some parameter..Please help.
