If I understood the case correctly,
Test :- 3 node ZK cluster, 600 sessions each will do one read operation(getChildren call)
every one minute.

I'm assuming the calls are equally distributed in time frame and it would be like : 600ops/60secs,
average 10 ops/sec will go to 3 node cluster
I also feel it should be, also it would be great if you publish the results after your tests.

Thanks that is also quite useful.

For my above use case, I just need to get the children of a particular znode.. And that's
what will be happening from all the 600 application machines..
