Performance consideration – Queue<T> versus ConcurrentQueue<T>
We should use ConcurrentQueue in the following scenarios, where it has slight or very big performance benefits over queues:
- In a pure producer-consumer scenario, where the processing time for each item is very low
- In a pure producer-consumer scenario, where there is only one dedicated producer thread and only one dedicated consumer thread
- In pure as well as mixed producer-consumer scenarios where the processing time is 500 FLOPS (short for Floating-Point Operations Per Second) or more
We should use queues over concurrent queues in a mixed producer-consumer scenario where the processing time for each item is lower, to gain performance.
