Concurrent and Blocking Queue in Java

Question

Answer 1

You can try LinkedTransferQueue from jsr166: http://gee.cs.oswego.edu/cgi-bin/viewcvs.cgi/jsr166/src/jsr166y/

It fulfills your requirements and have less overhead for offer/poll operations. As I can see from the code, when the queue is not empty, it uses atomic operations for polling elements. And when the queue is empty, it spins for some time and park the thread if unsuccessful. I think it can help in your case.
