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.
