Oh , and to give a better reply after reading that web page... I'd say
there might be a reason why 2.6 is slower (or appears slower) than 2.4
on some of those embedded platforms. It's definitely faster in a number
of areas on 6xx and other desktop CPUs. A lot of embedded folks will
then bitch and complain about the slowdown on their 8xx processor, but
very few of them if not none popped up actually identifying the actual
issues and coming up with solution for them during the 2.6 dev. cycle.
