--------------------------------

             Summary: Helix web admin performance issues
                 Key: HELIX-559
                 URL: https://issues.apache.org/jira/browse/HELIX-559
             Project: Apache Helix
          Issue Type: Bug
            Reporter: Zhen Zhang
            Assignee: Zhen Zhang


Helix web admin has a couple of performance issues:

- Use restlet default server which is slow
Need to switch to use jetty

- Unnecessary json deserialization/serialization
For reading idealStates from helix web admin, we read as ZNRecord, serialize ZNRecord to byte
arrays, and return the result. It's not necessary to do the der/ser which costs lots of CPU
cycles. Instead, we can read the raw data as byte arrays and return it directly.
