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):
org.apache.storm.shade.org.apache.zookeeper.server.NIOServerCnxnFactory.run()org.apache.storm.shade.org.apache.zookeeper.ClientCnxnSocketNIO.doTransport()
Is there any approaches to optimize the performance?
