[squid-users] Very high CPU ussage after migration 2.7 -> 3.5

[Sebastian Goicochea]

Something new:

Taking away all refresh patterns the CPU usage goes down to around 15%
Patterns look like this, maybe I have to change something:

refresh_pattern -i ^http://c2r\.microsoft\.com/ConsumerC2R/(.*) 43200 
100% 129600 override-expire ignore-reload  ignore-private override-lastmod

refresh_pattern -i 
^http:\/\/.*\.avg\.com\/softw\/.*\/update\/(.*\.bin)   43200 100% 
129600  override-expire ignore-reload  ignore-private override-lastmod


Thanks
