TPPS: A New Linux Kernel I/O Scheduler

The Tiny Parallel Proportion Scheduler (TPPS) is a new I/O scheduler for Linux to appear on the kernel mailing list.

Robin Dong explains in his mailing list announcement for this new I/O scheduler to use cgroup on high-speed devices., "We want to use blkio.cgroup on high-speed device (like fusionio) for our mysql clusters. After testing different io-scheduler, we found that cfq is too slow and deadline can't run on cgroup. So we developed a new io-scheduler: tpps (Tiny Parallel Proportion Scheduler).It dispatch requests only by using their individual weight and total weight (proportion) therefore it's simply and efficient."

The kernel configuration description describes this new I/O scheduler as, "The TPPS I/O scheduler tries to distribute iops proportional among all cgroups in the system. It should also provide a low latency working environment, suitable for flash-based device."

Should this Tiny Parallel Proportion Scheduler I/O scheduler gain steam and be on track for merging into a future Linux kernel release, you can bet it will be benchmarked on Phoronix.
