How do increase WCF Performance?

Question

Hi All,

 

How do increase the WCF start-up performance using XMLSerializer.

 

thanks in advance.

 

 

Answer 1

Why not consider using DataContractSerializer?  I did not compare the performance between XMLSerializer and DataContractSerializer.  However, DataContractSerializer is the default serializer for WCF and, therefore, I presume that it performs better than the older XMLSerializer.

Hi Pyeung !

 

Actually i was going to transfer a Large Data through DataSet . By what way It will increase and it use ful ?

is there any way to use DataContract Serializer ....

Hi Sami  Sir!

 

Please Refer this URL for XMl Serializer Performance http://seewinapp.blogspot.com/2005/09/xmlserializer-performance-issue.html

 

 

Answer 4

thanks sasi.

 

Will check and update you soon.

 

thanks

 

 

Answer 5

 

I tried with the XMLSerializer, but got warning as given below.

 

Command:

Svcutil.ext /t:xmlserializer "C:\Inetpub\wwwroot\service\sampleservice.dll"

 

Result:

Generating xml serializer...

Warning: Cannot generate xmlserializer for assembly file: C:\Inetput\wwwroot\service\sampleservice.dll\

No service contract in the Assembly has an Operation with xmlSerializerOperation Behaviors.

 

 

 

thanks in advance

Serialization and deserialization only helps in converting the data format.  I do not think it has real effect on transferring large data because data transmission occupies most of the time. If you are transferring large dataset via Http, you can consider compressing your data by using MTOM (Message Transmission Optimization Mechanism) Encoding (the default is Text Encoding).  If you are using Tcp, your message is defaulted to Binary Message Encoding (which is the most compact built-in format in WCF).

Hi Pyeung !

 

 I tried with Gzip compression but it wont increase the  Application performance. it consumes less than 2 seconds compared with dataset . by the way i am using WShttpbiningig with http Protocal but it does n't support to transfer as Stream. Is there Any other way to increase the WCF Srervice performance.

 

 

 thanks

 

Answer 8

WSHttpBinding supports MTOM but does not support streaming.

Answer 9

When you say performance, what dfo you mean?  Do you mean messages processed per second, total throughput, or some other measure?

 

WsHttpBinding doesn't support streaming due to the reliable messaging protocol (WS-RM), which requires that messages are buffered on either end - if you don't need this, then BasicHttpBinding or a custom binding might give you the performance you're looking for.

Answer 10

I mean total throughput. It takes more time to transmit data from server to client.

Rather than generating the serialization code in runtime, you may use the approach described in the link below.

For overall performance issues, refer to the link below. You may use performance analyzer to figure out what are the bottlenecks for your application.
