ConcurrentLinkedQueue for slow path

[Robert DiFalco]

You might find this interesting for your slow-path instead of using BlockingLinkedQueue.

For most of my tests this had a major impact on speed even if I used regular locking instead of parking.

Just for what it's worth...

Improving the slow path is on the plan for 2.4. As I recall my benchmarks, LinkedTransferQueue is faster than the approaches he show in that blog post, when it has items in it, but doesn’t cope as well with the empty or near-empty situations as I would like.

Cheers,

Chris
