The test result is placed at:
https://drive.google.com/file/d/0B49uX3igf4K4enBkdVFScXhFM0U

For some reason, the patches made the performace worse. The base tree is
today's Linus git 25364a9e54fb8296837061bf684b76d20eec01fb, and its
performace is about 1000MB/s. After applying this patch series, the
performace drops to 720MB/s.

Please let me know if you need more information, thanks.
