@szetszwo , thanks for working on this. Do you have time to do a patch rebase? I did a micro performance test, comparing the on heap buffer, off heap buffer and memory mapped buffer, here is the result.  By default, DN will use 1MB(bytes.per.checksum) as the buffer size. So using memory mapped buffer can increase at least micro level performance a lot. -- This is an automated message from the Apache Git Service.
