Re: Signal to noise ratio in Soap is very high

[Jim Murphy]

Can someone describe what the "slow part of web services is"?  If you 
think its the verbosity of XML I suspect your not measuring it against 
alternatives.  The fact is unless your message payload is very large the 
size of the XML body matters little in your overall performance - over 
broadband.

A great example of this is trying to optimize SOAP envelopes in the < 
1500 byte range - where many SOAP envelopes fall.  In this common case 
the ethernet frame size is packed up to ~1500 when you don't use all 
~1500 so "optimizing" from 1000 bytes to 500 just costs you.  Its costs 
you the time and complexity of the compression step.

When message sizes get larger it's still not the perf killer you may 
think - until messages sizes exceed !MB - YMMV.

Thank you for the responses.  I think it's possible to achieve
interoperability and small foot print.  It's just Soap was designed
lousy in this particular aspect.  When saying if speed matters, I think
most of the apps that has some kind of communication, speed does
matter.  I think there should be a new standard/version to replace Soap
if this cannot be addressed.

when your application is just too 'chatty' for SOAP...

SOAP is not designed to create compact dataflows.  It is designed for
interoperability and, because it is XML, extensibility.
IMHO, I would *not* use SOAP for purely internal processes if
speed or stream size matters (where faster/smaller) is better.
In that case I would go strictly with a socket-level approach.
Just my 2 small coins,

I look at a message send back from the server to a client in Axis,
and was very surprised that most of the text is not the data that I
need to send, but declaration and long namspaces.  Is it possible to
reduce these down and still comply with Soap?
Thanks,
