This test has 910 clients (sessions) involved:

We have users with 10k sessions accessing a single 5 node ZK ensemble. That's the largest I know about that's in production. I've personally tested up to 20k sessions attaching to a 3 node ensemble with 10 second session timeout and it was fine (although I didn't do much other than test session establishment and teardown).

The network of this test is a gigabit ethernet, ok? You know someone with was running ensembles in 100 Mbit/s ethernet?

Can Zookeeper ensemble runs only in memory rather than write in both memory and disk? This makes senses since I have a high reliable system? (Of course at some time we need a "dump" to shutdown and restart the entire system).

Well, the disk IO or network first limits the throughput?

Thanks for you quick response. I'm studding Zookeeper in my master thesis, for coordinate distributed index structures.
