Hello.

I'm running a Windows 2000 server machine with .Net Framework 1.1 and
Commerce Server 2002.
Since the application we had was changed to make XML/XSL transforms we are
getting the ASPNET_WP process reaching 100% usage of cpu. Even with hardware
with 4 Dual Core processors.
I've tested almost all of the code for proper closing of sql connections and
dispose situations and I can't seem to find anything out of the ordinary.
We have run alot of counters on this machine and we have identified a lot of
work of %Time used in GC. Also when sessions go above 300 more or less the
situation is really impossible to maintain. IISReset is the only solution.

Does anyone has some indications of what could be the problem?

Thanks.

Regards,
Pedro

are running on plain 1.1, its quite scary to read this:

Get a better picture of the performance counters and what they say here, it
might help:

XML/XSL transforms are cpu and memory intensive, but they can be optimized
to behave well.

Thanks Laura.

I have SP1 installed on 1.1 version. For the post fixes I will have to check
which ones may be missing.

What kind of optimization do you recommend for the transforms?
We have checked for infinite loops and everything is ok, we have removed
indentation from the xslt to reduce load time for the customer, and we
usually use stringbuilder for the concats.

Pedro
