I have been asked to increase the size of the proxies cache.
The proxy is running on a p120 w 80mb of ram and a 8gb hdd in pio mode.
It is also a default gateway, but due to the stupidness of some of the m$
machines on the network who refuse to address the Linux box 'even though its
ip is specified as the default gw' we have to run a proxy service to force
the end user's browsers to reference the DSL connection on the Linux box as
opposed to the 'expensive' isdn connection on the NT machine.
My question is what is a reasonable value to set cache_mem to? I have read
on some squid mailing list that 1/3 of the available memory would be a good
idea. But 1/3 of 80mb 'real' and 30mb swap might tie up the box in reading
from the hdd if 10-15 users were simultaneously making numberous requests
against the proxy.
Basically 'others' would like to download lots of the same files onto
numerous client machines so I have to build a reasonably sized cache as
opposed to my instinct to build a minimal one.
