Eliezer,
I cannot say by client or network. But, for sure I can say we have around 7000 computers using squid as a proxy.
Thanks,
Naresh

For how many users this squid should act as a proxy?
Ie client, machines,networks?

No this a physical box and we are using only for squid. We have 4 cpu's and
16 cores. Please find below for reference Accesslogs : redirected to /cache/squid

Hey,
Let start from 0.
How many CPU's and\or core's are on this machine?
Is it a VM?
How many users will be sitting behind this proxy?
Depends on the above we can decide on the right approach.

Hello Eliezer,
We are using OS "Redhat 7" and squid version 3.5.20.
As of now we are not using any cache, we already commented out. You want me try using cache by uncommenting the following line.
# Uncomment and adjust the following to add a disk cache directory.
#cache_dir ufs /cache/squid 10000 16 256
Thanks,
Naresh

Hey Naresh,
The RAM you need would differ by the nature, hardware and couple other things about the nature of the machine.
What you need is start from the bottom and move up.
List for yourself the machine specs and your goals.
It really helps to start from low ie the default 256MB ram cache and without any cache_dire and then see how it all moves on from there.
For now you are getting to the 19 hours of up time and you need to overcome this so just start with a dry run of no disk cache at all and stick to squid defaults for the next 24-48 hours.
Also what OS are you running?
Eliezer

Hello,
I am new to squid. I am getting a problem every 19 hours squid takes all RAM memory, then started taking swap in 20 minutes my swap is full. Then server side (OOM) is activating and killing all squid child's then finally killing squid parent. Can someone help me how to address this problem?
Why every 19 hours my memory is going to full?
How much Ram do I need for following squid version?
Squid Cache: Version 3.5.20
total used free shared buffers cached
Mem: 11845 2713 9132 14 71 1641 -/+ buffers/cache: 1000 10845
Swap: 25551 421 25130
Thanks,
Naresh
