> 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.
