Matteo Bertozzi commented on HBASE-5792:
----------------------------------------

Don't know if it makes sense catch the InterruptException, since we're trying 
to test write performance with nThreads... if we lost one thread, the test 
doesn't reflect what we've asked for.

> Related to HDFS-3280 and the HBase WAL slowdown on 0.23+
> It would be nice to have a simple tool like HFilePerformanceEvaluation, ...
> to be able to check easily the HLog performance.
