Not blindly. You should first use cache manager's "info" to have a
general idea of Squid's behaviour, use "ps -aux", "vmstat 300" and "free"
to get an idea of memory use (Squid's main problem), try to copy huge
files from/to the cache directory to see if the disk bandwidth is the
limiting factor, try to copy huge files from/to the network to see if the
cable is the limiting factor, etc.
