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

We had the same problem, and I ran a perf trace, and found that the
SoapHttpClientProtocol constructor does a lot of reflection to generate
serialization information.  Even if we used SGen to generate the
serializers, there were cases where it still took 7 seconds to run the
SoapHttpClientProtocol constructor the first time (after that it was
cached).

We fixed this by starting a thread and constructing the object (but not
running a method) in the thread at app startup.  That way we didn't have a
big slow down the first call.

.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
