Nick Dimiduk commented on HBASE-12040:
--------------------------------------
I've redone my test from yesterday with the following changes: (1) made sure
the RS process was cycled between loading data and running the PE; (2) run PE
test 10 times each. These results are the mean after throwing out the fastest
and slowest result in each set (same as [~jmspaggi]'s report). I'm only looking
at the overall run time, not the response latencies, though I have the logs if
you want further analysis.

Looks like branch-1 has some nice improvements going on :)

>
> While testing 0.99.0RC1 release performances, compared to 0.98.6, figured
> that:
> - FilteredScanTest is 100 times slower;
> - RandomReadTest is 1.5 times slower;
> - RandomSeekScanTest is 3.2 times slower;
> - RandomScanWithRange10Test is 1,2 times slower;
> - RandomScanWithRange100Test is 1,3 times slower;
> - RandomScanWithRange1000Test is 4 times slower;
> - SequentialReadTest is 1,7 times slower;
> - SequentialWriteTest is just a bit faster;
> - RandomWriteTest is just a bit faster;
> - GaussianRandomReadBenchmark is just a beat slower;
> - SequentialReadBenchmark is 1,1 times slower;
> - SequentialWriteBenchmark is 1,1 times slower;
> - UniformRandomReadBenchmark crashed;
> - UniformRandomSmallScan is 1,3 times slower.
