Duo Zhang commented on HBASE-17917:
-----------------------------------
The result is optimistic.
The commands are the same with above.
One Thread Test
PREAD : ~220s
STREAM : ~187s
DEFAULT: ~187s
Ten Theads Test
PREAD : ~32s
STREAM : ~27s
DEFAULT: ~27s
Notice that I've removed the streamLock in HFileReaderImpl as we will always
create a new reader for stream read now, so the result of 10 threads test for
STREAM is also much better.
I guess you will like this, sir [~stack].
> Use pread by default for all user scan
