Hello Gustav,
JCiP (the book Java Concurrency in Practice) contains a comparison of LBQ
and ABQ (ArrayBlockingQueue) and demonstrates that LBQ "scales" better on
multi-core machine (that they chose). Is a similar comparison available
somewhere with regards to LTQ and LBQ?
Also, will it be better if we created a Java 1.5 maven artifact of these
classes rather than checking them into SCM?
Regards,
Kedar
