Question

Is there another c# class for threads, which works faster ?

Answer 1

Based on your comment, you are using the Thread class in the System.Threading namespace.

Based on that, none of the classes are going to make the code that executes on the thread any faster; the best you can do is optimize the performance of the mechanism that you use for your situation.

That said, there are some things to be aware of:

• The Thread class probably has the most overhead; every time you create one, it creates a new managed thread, which might create a new OS thread. This is not an inconsequential operation.
• Using the ThreadPool class to schedule operations can be faster in terms of starting your operation, as it keeps a cache of threads already created so you don’t have to pay that penalty. The trade-off here is that a) many classes in the .NET framework use the ThreadPool to schedule tasks, and your task will be placed in a queue; there’s no way to force it to execute immediately when placed in the ThreadPool.
• The Task and Task<TResult> classes in the System.Threading.Tasks namespace run on top of the ThreadPool (this can be configured otherwise, to run with new Thread instances every time, for example), so you gain those benefits, but at the same time, there is overhead for cancellation, continuation, etc, etc. You gain ease-of-use here (much in my opinion), with minimal overhead.

In the end, you will have to measure what is best for your application and apply that solution; like most, there is no one-size-fits-all solution.
