High performance wcf

Question

How do I maximize performance for my wcf service? Is it possible to take advantage of multicore? or multi-threading?

Thanks!!

Answer 1

This is a very broad question that is difficult to answer. It will depend on what your service is doing and how it is implemented. But as a general rule of thumb you should avoid long running operations which could monopolize worker threads.

Answer 2

If you host your WCF service in IIS, then IIS will place each call on it's own thread, giving you the advantage mulitcores on your server.

If you want a single call to run on many threads, then you need to program this yourself in your code. You would only need this if your service is doing a lot of calculations.

Answer 3

The following Behavior properties default to the simplest (single threaded) solution, changing them from their default values will give you multiple threading, including self-hosted services.

• ConcurrencyMode default is Single (single threaded)
• UseSynchronizationContext default is True (effectively single threaded in UI self hosted scenario)

You may want to also look at InstanceContextMode also this MSDN article gives a starting point on WCF Concurrency.
