regions per server

Hi,

Current HBase cluster has close to 800 regions per RS with data uniformly
distributed across the nodes. could someone share their thoughts on
following options for efficiently decreasing # of regions/server?

* Increase region file size from 10GB to 50 GB: What is the impact on
queries by increasing region size from 10GB to 50GB? Would query latency
increase 5 times?
* Add additional servers to the cluster: Why is [20-200] an ideal range for
number of regions per RS? Can a RS handle over 1000 regions?

Best...

Have you read http://hbase.apache.org/book.html#ops.capacity.regions.count ?

Cheers
