Re: problem: Calling Java webservice performance .net 2.0 vs .net 3.5

If the creation of the proxy was inside the loop then I would have said you
were definitely on to something as, when using the generated proxy class, in
3.5 (maybe SP1) they cache the ChanelFactory whereas in 3.0 they didn't.

But from the OP code they create the proxy outside of the loop so the
caching of the ChannelFactory can't be the issue. However, the
infrastructure could still be different and do exactly as you are saying.
Wire Shark should show either way
