Yes, but... please define cache gain. speed? bandwidth? other?

Most of the log analysis tools provide measure of speed and bandwidth in
some form or another. IIRC its called cache gain by Calamaris. savings
by others. The Squid internal cachemgr calls these measures the Hit
Ratio.

As much as you can afford to purchase.

IIRC there is a general rule-of-thumb indicating 40% of your port-80 
traffic over a 7 days period was good.


Both RAM and disk space are easy to add or change as needed later.


please suggest me what factors should i have to keep in mind when my
purpose is cache gain...?


There is only one factor: how much data is being stored in and served 
from the cache. Use the latest releases and watch your MISS traffic very 
closely.


HIT ratios are the big ones. So far we have benchmarks of up to 55% HTTP 
traffic in ISP situations.


You may want to also see the http://wiki.squid-cache.org/SquidFaq on 
operating Squid.
