Re: [squid-users] Problem: high use of processor time

How many clients are simultaneously accessing the Internet through the
cache, and what is your Internet connection speed?

How long after the system starts does it begin to hog the CPU usage, and
does it slowly build up or suddenly jump to using 99.9%?

Regards,

nry
