Thanks for looking at 1133 also, Stack. I linked it to 1084,
that's good enough for me.
With ~2400 regions I needed to up the FD limit for datanodes
again, but after that, current HBase RC is able to restart
and is stable for me and performing well. I've never seen
load on my cluster this high without problems before. Very
nice.

BlockCache is enabled by default on catalog tables only. In the test,
it was not enabled for the user-space PE test table.
My experience with blockcache and random read was that with 1G heap,
tests usually ran slower when blockcache was enabled. Because the test
is 'random', test was spending its time clearing and filling the cache.
If heap was bigger, 2G say, then blockcache made a difference and random
reads ran faster (2-4X faster).
Real loads are probably not random.
If you are considering enabling blockcache on tables, be sure to
consider findings in HBASE-1127; i.e. difficulty making the soft
reference cache run reliably.

Nice work!
Is the random read with BlockCache enabled?

Here you go J-D:
http://wiki.apache.org/hadoop/Hbase/PerformanceEvaluation#0_19_0.
4-5X improvement writing and scanning. Random reads are up ~25%.
I'm going to start a new table with numbers for concurrent clients so we
can track how this changes over time.

I think we're also due for a new PE comparison.
