Per-thread memory management in C#

Question

Continuing the discussion from Understanding VS2010 C# parallel profiling results but more to the point:

I have many threads that work in parallel (using Parallel.Fo

Answer 1

You could pre-allocate a bunch of objects, and keep them in groups intended for separate threads. However, it's likely that you won't get any better performance from this.

The garbage collector is specially designed to handle small short-lived objects efficiently. If you keep the objects in a pool, they are long-lived and will survive a garbage collection, which in turns means that they will be copied to the second generation heap. This copying will be more expensive than just allocating new objects.
