I have just done some updates while running 3.8.0-0.rc5.git0.1.fc19.
A couple of these machines were booted with slub_debug=- . They all
seemed a bit slower (based on my watching the updates and not real
benchmarks) than with
with the previous debug kernels. It isn't quite to show stopping
slow, but it's getting close. It might be the slowness I see with
debugging kernels for yum updates, is due to a combination of
multiple debugging features rather than a single one.
Disabling slub debugging at boot time, seems to help speeding up editing
preferences in firefox.
