Hi All, I have got excellent results of dm-ioband, that controls the disk I/O bandwidth even when it accepts delayed write requests. In this time, I ran some benchmarks with a high-end storage. The reason was to avoid a performance bottleneck due to mechanical factors such as seek time. You can see the details of the benchmarks at: http://people.valinux.co.jp/~ryov/dm-ioband/hps/
I took a look at your beautiful results! When you have time, would you explain me how you succeeded to check the time, bandwidth, especially when you did write() tests? Actually, I tried similar tests and failed to check the bandwidth correctly. Did you insert something in the kernel source?
