Comment (by simonpj):

 I'm more surprised about this.  Generally I expect runtime performance to
 improve, not get worse. I do profile runtime performance more carefully,
 but my only benchmark suite is nofib.

 Anything you can do to characterise what is slowing down would be
 extremely helpful. Providing benchmark programs would be extremely
 helpful.  Lacking either, and I know that both are hard for you, it's hard
 to know how to help.
