ramkrishna.s.vasudevan commented on HBASE-20188:
------------------------------------------------
bq.I dont think here the issue is perf numbers
I also did not mean actual perf numbers. I just said as the initial comment
suggested abysmal performance. So it is not numbers but just that things are
slower on testing.

> How does 2.0.0 compare to old versions? Is it faster, slower? There is rumor
> that it is much slower, that the problem is the asyncwal writing. Does
> in-memory compaction slow us down or speed us up? What happens when you
> enable offheaping?
> Keep notes here in this umbrella issue. Need to be able to say something
> about perf when 2.0.0 ships.
