Karthik Ranganathan commented on HBASE-6925:
--------------------------------------------
Where is the chunking (that JIRA had a lot of stuff to parse)? Right now, in
89-fb, the client's nio send buffers are at 128K, and the input stream that
reads from the nio buffer is only 8K. This change is on the server side. I
would hypothesize that scan (which return a lot of data) will benefit from this.

> from 8K to 64K in HBaseServer. This seems to increase scan throughput.
