Actually SLAB_DEBUG isn't /that/ bad (or at least, people seem used to the hit when running rawhide. [Or maybe everyone has fast enough CPUs to make it not a big deal these days :) ]). The real killer that I get complaints from is CONFIG_DEBUG_PAGEALLOC. That one is only on as a last resort if I'm chasing something elusive that slab debug isn't shaking out.
