Dear Wiki user,

The "ZooKeeper/ServiceLatencyOverview" page has been changed by PatrickHunt.

--------------------------------------------------

  I also did not use the --server flag, again, I did some limited testing with this and afaics
there is no benefit to using this option with a ZK cluster.
  
  It would be interesting to test other workloads. Here I've weighted things more to a balanced
write/read workload. In production deployments we typically see a heavy read dominant workload.
In this case the service performance should be even better than what we are seeing here.
+ 
+ Additionally it might be interesting to try tuning the ZK configuration parameters. For
example to examine the effects of leaderServes and forceSync options (to name just two) on
overall performance and latency.
