I have a service that uses a fairly expensive object to create. I would like to improve the performance from call to call.

When I remove the object and run a load test, like how many invocations I can do per second, I have a massive performance difference between to situations.

Situation 1. I remove the expensive object: Invocations per sec ~= 130.
Situation 2. I use it as normal, with the object: rate is ~= 2 per sec.

I have a .NET WCF service hosted on an IIS 2008 server.

I was wondering if there was a way I could create an object cache/pool and hand those objects to each invocation of the service.

Any thoughs/comments that may help this situation?

    You could run the WCF service in per session mode and create the object using the singleton pattern, that way you only create the object once per session, as opposed to once per call.

    You may also be able to cache the objects using enterprise libray caching.
