See #4 here: http://zookeeper.apache.org/doc/r3.4.5/zookeeperProgrammers.html#ch_gotchas. If the volume holding the transaction log has slow I/O rates, then your Zookeeper will be slow too.

Currently we run ZK on small dedicated servers, but I'd love to move them to XenServer if the performance is good enough. I haven't been able to find much advice on this, so I'm hoping the users here will be able to tell me if this is a bad idea (or if there's some best practices for making it work). Any thoughts would be helpful. Thanks, Patrick
