Im using Generic.Queue in C# 3.0 and Monitor.Enter,wait,exit for wait before consuming the queue (wait for the element to be enqueued). Now im moving to C# 4.

Can anyone suggest me which one is fast and best especially to avoid locks..

BlockingCollection vs concurrentQueue or any thing else...

Note. I dont want to restrict my producer

Thanks in advance..

BlockingCollection and ConcurrentQueue are there for precisely this reason. I doubt that you'll find anything better, or simpler to use. The parallel extensions team know their stuff :)

Just a quick check on versions though - you're definitely using .NET 4, not just C# 4? (For example, you could be using Visual Studio 2010 and thus C# 4, but still targeting .NET 3.5, in which case you couldn't use Parallel Extensions.)

You may also want to start researching Task-Based Asynchronous Pattern, TPL Dataflow and the async/await features of C# 5... obviously you can't use them just yet, but it doesn't hurt to know what's coming up.
