I'm not the one with the problems :-)
It's safe to assume that the final version with the latest updates is
being used.

I never tried it on XP.

To run the server you should download the files I mentioned earlier,
there is a "run" script in there.

For running the benchmark with ab you can download this sample SOAP payload:
<http://dl.getdropbox.com/u/279023/getorder.xml>

and then run ab:

ab -c30 -n500000 -k -p getorder.xml -H 'SOAPAction:
"uri:WSTestWeb-TestService/GetOrder"' -T "text/xml;charset=UTF-8"

Apparently there are issues with dropped connections, stability under
load and ability do deal with an increasing number of connections, not
only with ab but also with their own testing tool. The problems seem to
get much worse when running on Windows 2008 with a 64bit JVM.
