HTablePool
There is a HTablePool class in org.apache.hadoop.hbase.client package. I was
wondering is there any performance advantages/speedup in using the pool
instead of HTable?
Thank you

I checked out 0.90 and now I see the difference :) Thanks.

I assume your question is for HBase 0.90.x
All HTable instances used in HTablePool share the same Configuration, and
this is still one zookeeper client only.
Reducing zookeeper connections has performance advantage.

Not that I know of. The Pool is of HTable instances.
