Subject Re: [VOTE] The 1st hbase 0.94.21 release candidate is available for download

Note that in order to compare apples to apples the instances should be configured the same.
0.98 increases the block cache to 40% by default, enables scanner caching by default, and
disabled Nagle's (I think).
The same config changes should be done to 0.94 (unless we truly want to compare the out of
the box configurations).

Here are the perfs tests results. Someone on the user list asked few days ago about perfs
between 0.94 and 0.98. So I have put also 0.98 on my results here. Basically, as I said yesterday,
no negativ perf impact for 0.94.21. Each test run 10 times (except the last 4) and I remove
the 2 extremes.

So far performances are similar to 0.94.21. So green from my side too. I will post detailed
results later tonight or tomorrow morning.
