I wish people would stop trying to deny that we have serious work in front of us 
to get the VFS and disk IO figures back to where they were before.

there ARE slowdowns and I have seen it both with tests on teh basic hardware and 
throug the filesystems.  I don't know why this surproses people because we have 
still a lot of work to do in teh interrupt latency field for example, and I 
doubt that even PHK would say that there is no work left to do in geom.
Where we are now is closing in on "feature complete". Now we need to profile and 
  optimise.
