Re: Squid 1.2 eating CPU time

 I saw the similar behavior on our systems.

 When given some work (under 5~6 requests/second), the cpu load is
 under 0.05. But the cpu load increases very rapidly as the increasing
 the requests.

 When the requests are 40~50 per seconds, the meter of cpu load increases
 upto 10.0 ~ 16.0. The squid uses the most cpu time, and the most cpu time
 was system mode (not user mode).

 The odd thing is that there are still 15~30% cpu idle when the cpu load
 indicates above 10.0.
  
 Our system configuration is:
        Linux Kernel 2.0.34
        Pentium-II 266Mhz + 256M memory + 4*3 giga Disk
        Squid-1.2beta22 (enable_snmp,async_io,NUMTHREAD=128)
