Hi Ying. I have no idea what these confusing numbers mean.
Is your benchmark running faster (good thing) or slower (sorry, but we
fixed a bug)
Thanks.

The benchmark running slower now. This has big impact on performance,
maybe we can find some clue to optimize from the test result? The
benchmark is about file IO performance on a loop back mounted NFS.
