I followed the quickstart instructions at https://kafka.apache.org/quickstart and everything seems to be working ok, except that commands take a long time to run, e.g.
$ time bin/kafka-topics.sh --list --zookeeper localhost:2181 real 0m11.751s user 0m1.540s sys 0m0.273s The zookeeper logging shows that the request is processed in a few milliseconds, so I think it's related to the kafka JVM configuration. If I remove com.sun.management.jmxremote it's takes 6 seconds but this is still much longer than I would have expected. Any suggestions on how to speed things up?
