I have file a JIRA bug https://issues.apache.org/jira/browse/ZOOKEEPER-1049
We have measured I/O wait again, but found no IO activity due to ZK. Just regular page cache sync daemon in the work: 0-3%. I will have my team to attach ZK stat result. Thanks a lot. Let's move this discussion to JIRA 2011. 4. 15., 오전 7:34, Ted Dunning 작성: > You said that, but there was some skepticism from others about this. > > You need to try the monitoring that was suggested. 5 minute averages are > not useful. > > What does the stat four letter command return?

We have a boot disk and usr disk. >> But as I said, disk I/O is not an issue that's causing 8 second delay. >>
