problems with speed trought proxi squid

Ignacio Rodríguez Arrós — Fri, 28 May 2004 03:22:47 GMT

I have a proxi server with squid, and sometimes it happens that if you use internet trought the proxi (squid), it canÂ´t download the pages (it is too slow, it looks like the speed of the conexion is too low), but if you make the conexion without going trought the proxi, (directly by the gateway), it is all right.And this not happens always, only sometimes....

Try to increase the amount of memory that squid uses.
It's best to have an appropriate hardware,i.e. if there are lot's of users-then the nic shoud be 1GB,lots of memory,fast hard drive,etc.
Are there any special rules in the configuration?

I think itÂ´s not a problem off memory or disk, there are a few users, the disk is empty, and the machine only works with squid, firewall, and mail server (for a very few users

How can i see that parameter ???

search the /etc/squid/squid.conf
for cache_mem
the number that appears next to it -is the amount of memory.

Hi,

paste the following file here...
/var/log/squid/cache.log
/var/log/squid/access.log

to chk how much memory Squid is using try
#ps -ef | grep squid

Excuse me, i have been out till now.
In my squid.conf, all the lines about cache are commented (with #), realy the only lines without # are the ones about acls and permisionss?? (sorry, i am new in squid).
the file attaches is my squid.conf

Re: problems with speed trought proxi squid

right!
locate the line # cache_mem 8
remove the comment mark from it, then change 8 with let's say 64 and restart the squid service.
See if there's an approvement in performance.

I have changed the line, put cache_mem 64 KB, save the file and executed squid -k reconfigure. Is that enougth?

Re: problems with speed trought proxi squid

Alexander Chuzhoy — Mon, 31 May 2004 05:09:02 GMT

cache_mem 64 MB
not KB

after changing execute:
service squid restart

Re: problems with speed trought proxi squid

Ignacio Rodríguez Arrós — Mon, 31 May 2004 06:02:16 GMT

I had put MB, not KB sorry. If i execute squid restart, it says service squid already running, is not valid squid -k reconfigure?

Re: problems with speed trought proxi squid

Alexander Chuzhoy — Mon, 31 May 2004 06:16:43 GMT

that works too, however it's better to restart the service .
if you can't restart the service with:
service squid restart

then use
servce squid stop
and
service squid start

P.S.
Points assignment is appreciated..

I am sorry to say that it seems to be as always, when the proxi is slow, if you go out directly bypassing it, it works well.
I donÂ´t know why

Try not to use authentication...
From your configuration file:
it shows that you use authentication ,i.e.
user has to be authenticated .Try to disable this feature temporarily- see if there's a big difference.
Don't try to connect to local address (from local subnet) using proxy-(it works slow on
Squid an on ISA) .

Hi,

Read this for optimising ur squid..
http://squid.visolve.com/squid/index.htm

I use DiskD for better performance
http://www.squid-cache.org/Doc/FAQ/FAQ-22.html

i had modifies ur conf....use it and see if it gives u better speed....
note: i had defined port 8080 not the usual 3128....i had modified this file in windows...so telnet to ur linux box and copy paste this configuration in /etc/squid/squid.conf..

Thanks for your squid.conf, i am testing it, but i want to use password for my users, (i put the proxi to get that), so i uncommented the lines about password. In a few days iÂ´ll tell you how the proxi work
