If I recall correctly avg_latency is an int, not float.I remember
someone wanted to replace it with a float sometime recently.
Correct me if I'm wrong.

Hi Ram,
ZooKeeper is very fast if deployed according to recommendations (nodes
onthe same network, directly connected). It's possible it gives 0
latency onavg, although usually it's a bit higher.I can recommend
Patrick's smoke test if you wan't to test performance.Especially zk-
smoketest and zk-latencies.py. It has a good readme:

But "mntr" command is pretty much the easiest tool out of the
box.Especially if you are on 3.4.x
