Linux 3.15 Kernel I/O Scheduler Benchmarks
After writing yesterday about the BFQ I/O scheduler update with its hopeful intentions of landing within the mainline Linux kernel, some readers wrote in about updated I/O scheduler results... Here they are.
I had some time yesterday on an idle Intel ultrabook system to run some Linux I/O scheduler benchmarks using the latest daily version of the Linux 3.15 kernel in its latest development stage that will be finalized in the weeks ahead. The I/O scheduler tests with a variety of open-source disk benchmarks were done using the default I/O scheduler options of Noop, Deadline, and CFQ.
The Intel Ultrabook obviously was running from a high-performance SATA SSD during testing.
For those looking for information on how to tune their kernel's I/O scheduler, Red Hat has in-depth documentation.
You can find more of these Linux 3.15 Noop, Deadline, and CFQ I/O scheduler benchmarks via OpenBenchmarking.org for this quick benchmarking roundabout.
