The differences between Linux IO Schedulers

Filed under

The Linux kernel input/output scheduler (IO Schedulers) controls the way the kernel handles read/write to disks. Different I/O schedulers may have different impact on certain workloads. Here are the list of available Linux I/O schedulers:

1) Noop

Noop scheduler is the simplest IO scheduler available in the kernel. It does not perform sorting or seek-prevention. It is intended for devices that has no mechanical parts or is capable of random access such as SSD or flash-disk.

2) Anticipatory (AS)

Anticipatory is the default I/O scheduler for Linux kernel (2.6.x) until it was replaced by CFQ. It tries to optimize disk I/O by minimizing disk seeking/head movement whenever possible.

Linux Foundation LFCS and LFCE: Alberto Bullo

I started using Linux few years ago out of curiosity when my old computer started to get slow and wanted to try something lighter. At the time, I had a disk of Fedora lying around from a conference and managed to get it installed and working. Since then, I started using it for everyday tasks to get more familiar with the alternative software. I really liked the fact that I could select any distro I wanted and have full control of the operating system. I also used Linux for university projects and started to better understand how to use the utilities and services. Open source projects caught my attention when I started using them on my first job as they gave me the ability to adjust the features and code to my needs but also to contribute back to the community. I then started visiting open source conferences to get more involved and became a big fan of the initiative. Read more
