Subject: SOAP performance and unmarshalling/parsing speed

I have been playing around with SOAP a little (as a client), and I
really like soap4r.  I was able to get my SOAP client running without
too much trouble at all.

Unfortunately, the performance is fairly slow.  We have a SOAP web
service running on the localhost, but it still takes about 4-5 seconds
to get 150K of data.

I used the wiredump to put the request/response to STDOUT, and I
realized that the actual communication is happening very fast (easily
within .5 seconds).  However, it hangs for a few seconds after the
response is received, before finally returning.

I am guessing that the unmarshalling and parsing of the returned
envelope is what is taking the most time.  I have heard that Ruby is not
so great at XML parsing.

Lucky for me, the return is one big chunk of text, and I just need to
strip off the envelope and don't need any complicated parsing of the
internals.

So, finally, my question: What would be the quickest and easiest (in
terms of programming skill) of sending the SOAP call and getting the
resulting XML, but bypassing the parsing/unmarshalling?  I think I can
handle the parsing by hand.

Thanks,
Micah
