It seems more people are starting to confirm this issue:

http://foldingforum.org/viewtopic.php?f=44&t=11336

IMHO it's not *that* dramatic as some people there describe it ("Is it
the holy grail?") but if something makes your desktop "smooth as silk"
just like that, it might seem as a holy grail ;) In any case, there
clearly seems to be a performance problem with the mainline scheduler on
many people's desktops that are being solved by BFS.
