Hi Alexey,

After stabilizing on 100% Success Rate in heavy load on our application we started to perform CPU Usage profiling.
We have noticed (you can see the attached screenshot) that we are spending 66% from the CPU time in the org.glassfish.nio.DefaultSelectorHandler.select() method.
We are running the load with the following environment:

* Grizzly 2.3.21

* JDK 1.7.0_72-b14

* RHEL 5.X

Any advice on how can we improve the high CPU consumption?

Thanks
Uri
