Michael Park commented on MESOS-2353:
-------------------------------------
[~vinodkone] I've been working on a library to avoid all of the unnecessary
intermediate object construction going from C++ to JSON string representation
to improve performance. I'll send out a design doc based on experimentation and
prototyping soon.
> Improve performance of the master's state.json endpoint for large clusters.

> Key: MESOS-2353
> URL: https://issues.apache.org/jira/browse/MESOS-2353
> Project: Mesos
> Issue Type: Improvement
> Components: master
> Reporter: Benjamin Mahler
> Labels: newbie, scalability, twitter
>
> The master's state.json endpoint consistently takes a long time to compute
> the JSON result, for large clusters:
> {noformat}
> $ time curl -s -o /dev/null localhost:5050/master/state.json
> Mon Jan 26 22:38:50 UTC 2015
> real 0m13.174s
> user 0m0.003s
> sys 0m0.022s
> {noformat}
> This can cause the master to get backlogged if there are many state.json
> requests in flight.
> Looking at {{perf}} data, it seems most of the time is spent doing memory
> allocation / de-allocation. This ticket will try to capture any low hanging
> fruit to speed this up. Possibly we can leverage moves if they are not
> already being used by the compiler.
