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.
