Marton Szasz updated MINIFICPP-1226:
------------------------------------
Fix Version/s: 0.9.0
> Improve C2 heartbeat performance
> --------------------------------
>
> Key: MINIFICPP-1226
> URL: https://issues.apache.org/jira/browse/MINIFICPP-1226
> Project: Apache NiFi MiNiFi C++
> Issue Type: Improvement
> Reporter: Marton Szasz
> Assignee: Marton Szasz
> Priority: Major
> Fix For: 0.9.0
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> During a profiling session I noticed that heartbeat serialization took about
> 30% of the used CPU time in a simple flow, with 1 sec heartbeat interval.
> This is way too long.
> In C2Agent::serializeMetrics, while constructing the payload, we used
> C2Payload's move facilities incorrectly resulting in a silent fallback to
> copy every time. This seems to have caused the high CPU usage. After the
> submitted change, heartbeat generation was no longer showing up in the my
> profiler view, so it should be significantly faster.
