Differential encoding indeed has better performance. But it is not really
compressing SOAP message. Instead, it reduces both payload data and
overhead in the SOAP message.
But as far as I know, currently no popular SOAP toolkit supports
differential encoding.

Thanks, good hint!

Does anyone know better compression techniques than gzip? I found a
paper claiming much better compression than gzip:

@inproceedings{Werner:CompressingSOAP,
       Author = {C. Werner and C. Buschmann and S. Fischer},
       Booktitle = {Proceedings of the IEEE International Conference on
Web
Services},
       Month = {July},
       Pages = {540-547},
       Title = {Compressing SOAP Messages by using Differential Encoding},
       Year = {2004}}

If my mind serves me right, I have also heard for years now, that people
are researching XML compression. Is there any advanced compression
algorithm available for Axis?

Cheers,
Chris
