Forums slow with IE but fine with FF

Hi guys,

Does anyone around here faced this problem or can give me any suggestions where to start looking for what is causing this?

Our forums ( is running slow with IE but fine with FF, especially during peak time (over 3,000 users online).

Here is a brief description of our configuration:

Three identical web servers (Dual Xeon 3 GHz with 2 GB RAM):
vBulletin 3.6.8 patch 2
Apache 2.0.63
PHP 5.2.5 with Xcache 1.2.2

One MySQL server (Dual Xeon 3 GHz with 4 GB RAM):
MySQL 5.0.37

The load balancing is being made using haproxy.

Thanks in advance,

Hi there,

I just make a quick test here and found out that if I disable haproxy and of course use just one web server, the forums becomes lightning fast (of course I did this in the middle of the night, when almost nobody is accessing our forums; during the day keeping the traffic in just one server would be insane). Otherwise the forums are very slow.

So I will play with haproxy later; since it uses cookies to track down which server each user is using, maybe it is a problem the way it sets cookies or some configuration with haproxy.
