Here is a list of tbench results with various kernel versions: 2.6.22 3207.77 mb/sec 2.6.24 3185.66 2.6.25 2848.83 2.6.26 2706.09 2.6.27(rc2) 2571.03 And linux-next is: 2.6.28(l-next) 2568.74 It shows that there is still have work to be done on linux-next. Too close to upstream in performance. Note the KT event between 2.6.24 and 2.6.25.
