Nick Dimiduk commented on HBASE-9806:
-------------------------------------
Moving to the io.hfile package makes sense. Maybe we merge this one into
HFilePerfEval, as these are closely related?
I'd like to add support for more schema varieties and access distributions on
PerfEval, similar to what these tools have. The whole business could use some
refactor toward more code sharing. It all depends on the goal of the tool
though. I like PerfEval because it's closer to what a user will see. OTOH, it
makes it difficult for an hbase dev to get a sense for the IO subsystem pieces
in isolation.

> We have at least three different block caching layers with myriad
> configuration settings. Let's add a tool for evaluating memory allocations
> and configuration combinations with different access patterns.
