RE: [squid-users] FW: Squid memory utilization

Ok, I have been all over the memory FAQs and still can't figure out why my
server is consuming all it's RAM. I have 2GIG of DDR RAM and the only
service running on this server is Squid. My cache_mem is set to 64MB and
cache_dir is 10000 16 256. During peak hours my RAM is consumed very fast.
Is there something else I should be configuring besides cache_mem and
cache_dir to minimize memory use?

Any help would be greatly appreciated!

First step is to figure out what part of Squid is using a lot of memory.
The Memory Utilization page in cachemgr is a good start.

I prefer colleding runtime statistics with SNMP and plot them using MRTG

For usage statistics use one of the log analyzis packages for Squid. Which
one to use depends a little on what kind of statistics you are interested

The FAQ chapter is still valid to most parts.

There is not much to do about these parameters. Already set for very
restrictive memory usage.
