.net SOAP toolkit performance for SOAP deserialization

[Prabhu]

Hi All.
We are building an ASP.net application using C# & .net 1.1 framework.
The ASP.net application consumes web services (Java/Apache Axis
implementation) and we are facing issues that the application is very slow.

Initially we suspected network and server side responses as culprits.
But on further investigation (we override GetWebResponse and GetWebRequest
methods SOAPClient) we have found that the application is spending
considerable amount of time (1+ minute) in deserializing the SOAP response
from the server.

We are using VS.net 2003 for generating the proxies.

Has anyone faced such performance issues and any suggestions?

 

[Dan Rogers]

Hi,

How big is the response? Are there other implementations of clients that
deserialize more rapidly?

Hi.
The responses are on an avg about 250K.
But the object nesting is quite deep (4 or 5 levels) in the WSDL (and the
proxy classes generated).

We are sort of first clients to these services, but there are some stubs
written in Java. We will try to measure deserialization performance in these
clients.

regards

 

[Dan Rogers]

In general a 250K response won't cause undue perf issues, nor will nesting
of a few levels. I would start to suspect constructor issues in the
classes that the XML maps to, but without a neutral test based on a schema,
and code output from a tool like XSD.exe or XsdObjectGen.exe, I'm unable to
troubleshoot this further.

If you can share schema or a reproducable end point where I can try this
out, I can help you more.

Regards,

Dan

Hi Dan.
Thanks for the help.
I am pasting the WSDL of the service below. The operation that is most
problematic is "getAirfareQuotes"

Meanwhile we still are trying to get performance numbers for Java clients. I
will update forum once we have some consistent results.

Hi Prabhu,

These are pretty big, and pretty complex message structures. I'd not be
surprized if you are experiencing constuction delays because of all of the
repeating array of array of array nesting going on. Have you the ability
to switch this service design over to a document literal design instead of
an encoded design? In that approach, you'd have more complicated class
member types, but you might see a difference in how the "constructor" delay
is effecting your performance (if it is a constructor delay at all). In
other words, have you thought about schematizing this design and not
treating the data as arrays of types that contain other arrays?

I can't promise it would help, but I've been able to get awesome
performance in literal design, and also this would make the service design
more interoperable and follow interop guidelines such as those published on
WS-I.org.

Hope this helps

Dan

In general a 250K response won't cause undue perf issues, nor will nesting
of a few levels. I would start to suspect constructor issues in the
classes that the XML maps to, but without a neutral test based on a schema,
and code output from a tool like XSD.exe or XsdObjectGen.exe, I'm unable to
troubleshoot this further.

If you can share schema or a reproducable end point where I can try this
out, I can help you more.

Regards,

Dan
