Subject Zookeeper in Kafka has gets a very low Performance
Date Wed, 12 Sep 2012 10:07:44 GMT
Here is what I haveļ¼š


   - zookeeper cluster with 3 severs
   - 1700+ kafka topics (that means there are 1700+ children under path
   '/brokers/topics'), these topics are written frequently by kafka.
   - log file size is 67108880 byte,  snapshot file size is 4192072
   byte, new log/snapshot files are created every one or two minutes

The problem is that it takes more than 40ms to getData of a single topic. I
have another zookeeper cluster and the getData takes no more than 2ms to
getData of a single path. This cluster doesn't server kafka.

Any body knows why the performance is so bad?

Many thanks and best regards.

Liwei
