I'd also suggest getting a capture of your data exchange so you can see if there are obvious ways to improve the representation and reduce the message sizes. Even if you're stuck using rpc/enc you may be able to improve performance by disabling multiRefs and xsi:type information in what Axis generates (check the Axis docs or mailing list archive for details on how to do this).

Would anyone be interested in discussing their experiences with SOAP performance and the types of applications they are running?
I am working on a SOAP based reporting system. The
average results set is 200 rows with 20 columns from a
JDBC data source. The data source is very quick and
not much of a factor in my tests. For one user we get
pretty decent results on a single processor, 3GHz
Windows server, which is 1 to 2 seconds per response. Things seems to scale fairly well until we get to 8
threads, when we get a response in about 8 seconds. At that point our Web server is completely maxed out
and performance gets really slow. by threads, I mean
JMeter test clients threads that I am using to put a
load on the server.
I know that SOAP servers have to convert all of the data to a SOAP response and send that result back to the client. So is what I am seeing normal, or should I be expecting better performance?
