Performance of Concurrent Collections in .NET 4

Performance of Concurrent Collections in .NET 4

.NET 4 introduces new data structures designed to simplify thread-safe access to shared data, and to increase the performance and scalability of multi-threaded applications. To best take advantage of these data structures, it helps to understand their performance characteristics in different scenarios.

Chunyan Song, Emad Omara and Mike Liddell measured the performance of four new concurrent collection types: ConcurrentQueue(T), ConcurrentStack(T), ConcurrentBag(T), and ConcurrentDictionary(TKey, TValue), and published their findings in this paper:
