Linux 3.16: Deadline I/O Scheduler Generally Leads With A SSD
With BlogBench, Noop was behind deadline and CFQ schedulers.
CFQ had a slight advantage too with the Threaded I/O Tester.
With some of the other tests, there was little change between the mainline Linux kernel I/O scheduler options.
Overall, with the Linux 3.16 kernel on the SSD-backed system the best performance was generally found when using the deadline I/O scheduler. Using deadline for SSDs generally leads to the best performance, at least for most single disk systems I've encountered, and with Linux 3.16 it's no different. HDD tests and other Linux 3.16 benchmarks are forthcoming on Phoronix.
