Re: [squid-users] memory utilisation

<Note: Trim your messages when posting new subjects, particularly when

the end of your post (a discussion between you and I about Frox, FTP,
and a few brief mentions of Squid). Many people are on expensive dialup
accounts and pay per minute for downloading thei mail.>

That's 64MB of swap used in your top output. Squid is taking 94MB,
which seems about normal for a Squid with 8GB of cachedir running diskd
(why diskd on Linux? it's a less effective alternative to asyncio--but
if memory is a concern, don't use either). Something else is using a
large plot of memory on the system as well, though it's not in your four
lines of top ouput. If your box is being used primarily for Squid (and
I recommend it, since you are running an ISP through it), then you
should remove all other memory eating programs. If Frox is what is
taking up the rest of the memory, then you should probably remove it or
add more memory. Running Squid on a box that is going into swap memory
is not effective, and will be slow (as you've reported your Squid is
several times).

Your Options:

Reduce cache_dir size.
Remove Frox, or whatever is taking a large plot of your memory (it's
probably a bigger process than Squid whatever it is).
Add more memory.

That being said, a 192MB Squid box can easily support your load and your
cache_dir sizing...There is something else on your system eating up some
of your memory, causing things to go into swap. Perhaps Frox has a
memory leak--it is considered alpha or beta quality software by it's author.
