Subject Re: Performance optimize on local mode.

Local mode is quite different from how distributed mode would work. I would suggest that you
create a distributed setup(with even a few nodes is enough) - Running a Multi-Node Storm Cluster
- Michael G. Noll -  and then profile the individual workers to find what is consuming the
most CPU (which I'm assuming is your intention).

We are replaying our data on Local mode storm cluster. Using jvisualvm, we find most CPU
are used by following methods (about 60% CPU time):
Is there any approaches to optimize the performance?
