> Turning off all file I/O, and running the PerformanceEvaluation test, of
> 1,048,576 sequential writes to HBase managed to achieve only 7,285 IPCs per
> second.
> Running PerformanceEvaluation sequential write test modified to do an abort
> instead of a commit, it was possible to do 68,337 operations per second. We
> are obviously spending a lot of time doing IPCs.
> We need to investigate to find the bottleneck. Marshalling and unmarshalling?
> Socket setup and teardown?
