Jean-Daniel Cryans commented on HBASE-8322:
-------------------------------------------
The really important thing is that you don't want to access disk, as it will
dominate your benchmark and you can't really control what will come from disk
and what won't at the beginning of the test. That's why all my tests where done
only once 100% of the data was in whatever cache I was using (block cache or OS
buffer).
> Re-enable hbase checksums by default

> Double checksumming issues in HBase level checksums(HBASE-5074) has been
> fixed in HBASE-6868. However, that patch also disables hbase checksums by
> default. I think we should re-enable it by default, and document the
> interaction with shortcircuit reads.
