Alek,
Thanks for the info. This is very helpful. One of the issues I have seen is
large XML data (imagine XML based data about provisioning the phone record
of say 20,000 subscribers - pushed at 3:00 a.m. Sunday morning) being
compressed before it is transported. The SOAP method headers can stay
uncompressed. In this case - there is also performance improvements.
Ofcourse there is slight delay in packing the XML data and then unpacking
them at the destination.

Have u done some testing with packed XML data as well ? 

For reference u can see:

XMLZip is free download.

hi,

we are very interested in SOAP/XML performance (especially for
RMI/distributed component communication) so we have written a paper about
it, see:

  http://www.extreme.indiana.edu/soap/index.html#perf

as part of this paper we have written a test framework that included
testing serialization/deserialization, size overhead and round-trip
performance and made available at:

  http://www.extreme.indiana.edu/soap/sc00-tests/

i have also performed a simple benchmark of different XML parsers over a
set of SOAP messages (small 2.7K, middle size 27K and big 2.7M) and did
some evaluations - results and source code available at:

  http://www.extreme.indiana.edu/~aslom/exxp/

i am working on second version of this benchmark with updated list of
parsers and i welcome all comments about it.

thanks,

alek
