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.
