ASP page slow in initial connection
Posted on 2008-06-13
I have a nasty question here which drives me crazy for the last week and I don't seem to get a answer from the net.
We just upgraded our datacenter, with a two new Firewalls, both a Juniper SSG-320m which run in HA.
I put some webservers and sqlserver in there and now the problem starts.
A regular unix machine with apache and PHP is fast as lightning, but in the same acces rule (port 80 untrust to front-end zone) a Windows 2003 IIS server hosting a heavy .aspx page takes literaly 21 seconds to load.
I see in my logs a session is created but the request to the server has a timeout of 20 seconds.
So even when I have stopped the application it takes 20 seconds to get the server error.
Yesterday I put the server directly on the net, and then the performance is fine, but now back behing the SSG's the error is there again. I had a play with the ALGS and virus detection, but it didn;t seem to work. Maybe it has something to do with the Adress translation.
Is anyone familiar with this problem or can tell me what to to, because I'm quite desperate.
500 for the winning answer.
