ASP.NET Stress Test ACT (Socket Errors)

[Guest]

I´m having this problem: I'm stress testing a ASP.NET web application using
ACT and comparing results with a previous version of the website (developed
in ColdFusion 4.5). When using 300 simultaneous users (about 25-30 rps),
everything works fine, although Cold Fusion seems to be a little faster than
ASP.NET.

When using 2000 simultaneous users (about 50-60 rps), Cold Fusion works
really fine but the application in ASP.NET starts to have socket errors. (See
the test results below). In this cenario TTFB min is ok, the average becomes
a little high and TTFB max is really high (85 sec), what does not happen with
Cold Fusion.

Anyone can say what could be the cause of this problem? Is it possible to be
a configuration issue of the framework? A Network problem?

ACT is running on a single WINXP SP2 station and the website is at a WIN2000
with IIS5 and .NET Framework 1.1

hard to know with this little info. could be configuration or your code.
what was the cpu, queue depth, etc. if you have cpu, and i/o to spare, try
upping the asp.net thread pool size. you may also need to up the ado.net
pool size.
