Re: Recommendations for Squid proxy hardware

A guy from the Squid development team recommeded a cache size of about the
amount of data that is transfered every 3 days. Assuming that all your 80
lines are doing 3KB/s and they are on average busy for half the day it makes
about 3G of storage.

If you are running out of RAM then putting in more RAM is an obvious first
But adjusting your Squid settings may be a better idea.
Also consider that 80*3KB/s = 240KB/s for Squid storage. You shouldn't
really need 3 fast hard drives to deliver this small amount of IO.
BTW You should also use ReiserFS if you haven't already done so. ReiserFS
is much faster for systems with lots of small files, and it gives a fast
reboot after a power failure.
