Hello! I'm use Apache JMeter for hit-based load testing apache cassandra with
netflix plugins. But, default logging of ResultCollector is really too slow. I
have lock artefacts at throughtput about 35krps with simple csv settings. In
thread dump i see many block threads on java.io.PrintWriter.println(). I write
writeback cache for PrintWriter and have more performant solution.
I showed it Phillipe M. and his patched my code:)
Performance comparsion of solutions:

My first patch is https://gist.github.com/sch1z0phren1a/5190889
Second patch with Phillipe M. changes is
https://gist.github.com/sch1z0phren1a/6bf25227b63a4d9e05f3
I tested it with simple Dummy Sampler from jmeter-plugins.
Test Plan is here https://gist.github.com/sch1z0phren1a/b65bf49de6a6f90efa18
So, what about include it into Apache JMeter? :)
Phillipe, thanks you!:)
