Yep, I did try this out a couple days ago to make sure XSOAP was doing this.

Hmm. I didn't use a timer for that one, so maybe it is faster, but I was 
feeling impatient so it didn't seem faster. :-)

We'll have to find some time here to look at the performance of the 
various underlying libraries. The 25 seconds I saw, or even the 8-10 
seconds you measured are really too slow.
