Slow IIS 6 after SP2 on Win 2003

Efter I have installed SP 2 on my Windows 2003 Server with IIS 6.0 the IIS
has become extremly slow. It locks up after 30-60 minuttes. The website has
6.000 users per day.
It worked OK during the night where the number of visits are low, but from 8
AM it started chrashing - thats when the users start browsing our site:-(

The server is a HP DL 380 with 2 dual core 3,4 GHz and 2 GB RAM.
I can reset the IIS and the page works great for a while. When I reset the
amount of used RAM is 800 MB and it works up to 1,25 GB RAM, and then stops
working. At the same time the CPU blasts away with 95 % usage:-(

The Framework is 3.0 and the server is fully updated from windowsupdate.

Can anyone come up with an idea to solve the problem?

Getting errors in the Event Log?

Running applications on the server? If so, what are they?

It sounds like your application code has performance and scalability
issues exposed by SP2. Nothing anyone can do about it other than to
debug and fix the website's code.

You may want to try tracking down what is using up the CPU cycles as
well as RAM with tools like DebugDiag.

Re: Slow IIS 6 after SP2 on Win 2003

-- I'd like to chime in here. We have a production server that is running
W2K3 server standard with SP1. All of our sites are working beautifully on
this server (the sites are running .Net framework 1.1). We just purchased a
new server that contains almost identical hardware with the exception that it
has a faster processor and 4GB of ram vs 2GB. The new server is running SP2.
We moved all our websites over to the new server. There were no code
changes. It was a simple file copy and setting up of the app pools/vdirs.

We are now experiencing random slowness on both static pages and dynamic
..asp pages. And sometimes these slowdowns can be measured in minutes (2-3
minutes). It is extrememly random and has been very difficult to pinpoint a
single issue.

Any ideas on what could be causing this? It is definitely not a code issue
because we haven't changed any code. The only thing that is discernably
different is that the new server is running 4GB of memory.

Suggestions?

Your help is appreciated.

Thanks.

Re: Slow IIS 6 after SP2 on Win 2003

Hi,

I have a similar problem.

I have a asp dynamic site that also receives over 6000 visitors per day.

Sometimes the ASP just stop working and people get presented with page
not found error.

At this time all HTML pages still work but not the ASP pages.

The only way for me to fix this is to restart the server.

This will then work for a few days and then boom, stops again.

Windows 2003 sp2

Also when I try to loop through a database to e-mail 100 e-mails, it
takes for ever and ASP eventualy gives up.

On my other server that is the same, it works fine.

I have an idea that some IIS files or something could be damange or
something.

Any ideas or help on where to look for what ?

Thanks

Hugo
