Hi

i have centos 5.3 server with squid proxy server configured on it

from last few days my internet is very slow , in my squid proxy
i cant defined any cache_mem (bytes) and cache_dir,it is as follows
#Default:

# cache_mem 8 MB

#Default:

# cache_dir ufs /var/spool/squid 100 16 256

1) as i not defined this tag then cache_mem and cache_dir how much squid takes by default
2)i need to define this tag to increase internet speed??

That is why it is slow.

uncomment those lines to check the difference.

Thanks for reply also can you pls tell me as i not defined this tag then cache_mem and cache_dir how much squid takes by default?

GlennsPref · 04-23-2013, 05:19 AM

Cheers, I think those are the defaults.

In particular I use more than that.

I'm just doing a re-install of my main system, where the squid system config file is.

but in squid.conf tag is as follows

# cache_mem 8 MB , as this tag contain # i.e in comment so how it take this default value as 8 MB

Right...it is 8MB BY DEFAULT, and the Squid docs can tell you this. Uncomment it and make it larger.

A better question would be why, since things were working ok, did it just start behaving slowly? What did you change?

That makes no sense.

If it WAS working fine, and now it isn't...that is a CLEAR sign that SOMETHING changed. What other diagnostics have you done? Have you checked ANYTHING on the system? The network? Router? Call your ISP?

This might seem like a really obvious question but sometimes we miss the obvious; did you try a machine that normally goes via the proxy and see if a direct connection (i.e. remove the proxy in its configuration) is better?

I'm running a squid proxy at home here, it's proxying traffic sometimes for up to 4 devices at a time, and I have not changed this default setting once.

Hi

i make cache_mem 32 Mb in squid.conf , but still internet is slow

GlennsPref · 05-03-2013, 06:26 AM

Hi, have you run as root,

Code:

squid -z

This sets up the cache directories. I certainly notice the difference....Just a thought...

Ok...so did you read/understand what was posted before??? AGAIN:

If it WAS working fine, and now it isn't...that is a CLEAR sign that SOMETHING changed. What other diagnostics have you done? Have you checked ANYTHING on the system? The network? Router? Call your ISP?

So, AGAIN...what changed? Based on what you posted, everything was great, then it started not working correctly. That doesn't happen for no reason.
