Linux 3.12 Kernel IO Scheduler Performance Benchmarks
Deadline, CFQ, and Noop I/O scheduler benchmarks from the Linux 3.12 Git kernel using an Intel Core i7 4960X Ivy Bridge Extreme processor on Ubuntu 13.10 base. Benchmarking by Michael Larabel of Phoronix.com. Just some quick tests for now... More on the way :)
