Loving kernel 2.6 now. > The big question is *why* Arjan's feels faster. The most obvious candidate is probably that HZ is defined to 1000 on mine (as it is upstream), and 100 in Arjan's. It would be useful if folks could recompile mine from source, and change HZ and see if that alone is enough to fix the 'sluggishness'. The relevant patch is below. (evo will probably munge it horribly, but it's only a one-liner which should be obvious to regenerate).
