No. No changes.
Two CPUs will mean that any other process that runs with or at the same
as squid will not take CPU away from the squid process. This meant
increases in performance for us, as we use the same machine for a number
different purposes (file serving, print serving, and associated resource
accounting). Squid itself doesn't make use of the 2nd CPU, but the OS
ensure Squid gets all the power it can out of the CPU it is allocated
For us, this was a significant improvement in performance... though it
be said that Squid is not a CPU hog even at the worst of times (it does
love memory, however).

My only suggestion is to ensure you have tonnes of memory on the
We found 512M to 1G to be ok. 256M is definitely insufficient. You
need to adjust the swap file, if you are going to increase the RAM...
