Slow https connections with Squid

hsmann

Hello to everybody in this forum !

We are using pfsense 1.2 with squid 2.6.21_11 and squidguard 1.2.0_1-2.

Https-Connections (eg. online-banking) via squid-proxy are very slow, sometimes timeouts occur.
We are not using the transparent option, no "sticky connections", no load balancing.

Without proxy (direct connection via router) https works fast.

We testet with Firefox and IE6/7. Both were slow with proxy.
Our users reported this problem 3 days ago, before it worked over a year without any problem and without any changes in the configuration.

I searched the web and the forum but couldn't find anything helpful.

Any ideas? Should I upgrade to 1.2.2 ?

Thx in advance

I would go straight to 1.2.3. RC3 has a ton of bugfixes and has been very stable (I am running it in production.)

Any other suggestions?

reboot server

Be careful!!!!!!

the first file is /boot/loader.conf, the second file is NOT /etc/loader.conf, should be /etc/sysctl.conf!

Thank you very much for your help.

Meanwhile I tried 1.2.3 RC3 and it works fine (up to now)!
I updated the squid/squidguard packages too.

In the past, every two weeks or so squid was hanging and had to be restarted,
so now I hope that this problem will be solved too.
