WCF - Scalablity

Question

Hi ,
   I have WCF Service with a basicHTTP binding running in 3.5 framework.I have a web method that accepts byte array and I deserialise to a dataset and load to a database.


I have written WCF client that makes 25 concurrent requests to the WCF , but my WCF responds very slowly it takes about 15 mins to respond to each request and few of the requests are throwing a premature end of file errors.

My WCF Server is a 4 GB RAM with x64 arch - windows 2003 server.


My binding mode or tranfer mode is already set to Streamed.

What could be wrong. I have enabled my tracing and I dont see any issues but one thing I observe is that it takes very less time to process the request but it takes very long time to receive the request completely....

Any help would be appreciated.
