[isp-caching] Re: unusually high cpu load with squid

["Masood Ahmad Shah" <masood@...>]

hmmm I will suggest better to compile squid source instead using Debian
package ............I have tested squid on FreeBSD, Solaris, RedHat Linux,
Man..ake Linux .....I did not find any problem regarding cpu. If you are
using debian compile pacakge on diffirent os ......that can be cause of the
problem :)

Best Regds,
