Hi James, thanks for your comment.

The results are as follows: o dbench [ 1/2/4 processes run parallely on 4-CPUs / 10 times trials ] - Average[MB/s] - -1proc- -2procs- -4procs- 2.6.8.1(disable) 247.43 473.11 891.51 2.6.8.1(enable) 218.99 434.97 761.06 2.6.8.1(+rwlock) 225.18 432.80 802.62 2.6.8.1(+RCU) 231.84 444.30 820.00 -------------------------------------------- (*) 2.6.8.1(+RCU) is applied the take3-patch.
By the way, the results of dbench are sharply changed at every measurement. I don't think it is statistically-significant.
