> Reduce PerfLogger isDebugEnabled overhead
> -----------------------------------------
>
> Key: OAK-3361
> URL: https://issues.apache.org/jira/browse/OAK-3361
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.3.4
> Reporter: Joel Richard
> Priority: Minor
> Labels: performance
> Attachments:
> 0001-OAK-3361-Reduce-PerfLogger-isDebugEnabled-overhead.patch
>
>
> If a node is cached, 1/4 of the time which is used to call
> DocumentNodeStore.getNode is spent in PerfLogger.start and PerfLogger.end
> just for checking whether or not debug logging is enabled (this is likely
> much less if no TurboFilters are used).
> To reduce the overhead of the PerfLogger, it should not check if debug is
> enabled in end() if start is below 0 anyway. Moreover, it would help to check
> only every second if debug is really enabled.
