why? i haven't found udev to be a significant performance hog
hald and dbus on the other hand .. well they aren't too bad but you
might have a point there
None of them are really resource hogs and these are fundamental
advancements which you cannot really downgrade without breaking a whole
lot of user space apps sitting on top of it. In fact for FC5 the whole
init system is potentially dependant on dbus

I've just got FC4 yesterday, and I'll be trying it out shortly - but
it is reported
to be significantly faster for most C++ code - that includes stuff
like Qt, KDE,
Mozilla, Firefox, etc.
because of gcc 4?
GCC 4 is not expected to be a big performance improvement at this point.
The framework for optimization from Red Hat is entirely new. see
http://lwn.net/Articles/84888/. Taking advantage of this framework will ;
be a part of the minor point releases like GCC 4.1. FC4 improvements
were as a result of other changes like boot code optimisation using
programs like bootchart (
http://bootchart.sf.net) along with other work
which has happened upstream
