[PATCH] BUG 11786 - squid: Remove setting for filter processes the number of Squid processes

["Daniel Weismüller" <daniel.weismueller@ipfire.org>]

[-- Attachment #1: Type: text/plain, Size: 3878 bytes --]

I added a function to determine the number of cores.
Now the number of squid processes will be equal to the number of logical cores.
Further I removed the possibility of changing the number
of squid processes in the proxy.cgi
