> JMH benchmark improvements
> --------------------------
>
> Key: CASSANDRA-18871
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18871
> Project: Cassandra
> Issue Type: Improvement
> Components: Build, Legacy/Tools
> Reporter: Jacek Lewandowski
> Assignee: Jacek Lewandowski
> Priority: Normal
> Fix For: 4.0.12, 4.1.4, 5.0, 5.1
>
> Time Spent: 50m
> Remaining Estimate: 0h
>
> 1. CASSANDRA-12586 introduced {{build-jmh}} task which builds uber jar for
> JMH benchmarks which is then not used with {{ant microbench}} task. It is
> used though by the {{test/bin/jmh}} script.
> In fact, I have no idea why we should use uber jar if JMH can perfectly run
> with a regular classpath. Maybe that had something to do with older JMH
> version which was used that time. Building uber jars takes time and is
> annoying. Since it seems to be redundant anyway, I'm going to remove it and
> fix {{test/bin/jmh}} to use a regular classpath.
> 2. I'll add support for async profiler in benchmarks. That is, the
> {{microbench}} target automatically fetches the async profiler binaries and
> adds the necessary args for JMH ({{-prof asyc...}} in particular) whenever we
> run {{microbench-with-profiler}} task. If no additional properties are
> provided some default options will be applied (defined in the script, can be
> negotiated). Otherwise, whatever is passed to the {{profiler.opts}} property
> will be added as profiler options after library path and target directory
> definition.
> 3. If someone wants to see any additional improvements, please comment on the
> ticket.
