Need Guidelines For Setting Compression Strategy on WCF services at IIS 8.5

HI,

I am currently working on project with a WCF service hosted on IIS 8.5. Some of the WCF service methods returning large amount of XML Data (Dynamic content) to the client with the SOAP Protocol .

Hence, to save the bandwidth for each packet of data (which is dynamic) over the network.We came over a solution of implementing the feature of HTTPCompression provided by IIS.

So, we are stuck up in deciding the compression level for dynamic content..

Anyone, can help me deciding what could be the idealistic compression level that should be set for dynamic content ?

Or, can you suggest me any other solution for this.

Thanks in Advance !!

Regards,
