[Andreas] has created this tutorial on real-time (RT) tasks in Linux. At first blush that sounds like a rather dry topic, but [Andreas] makes things interesting by giving us some real-world demos ...

Bugs in the Linux scheduler can cause performance degradation in heavily multithreaded loads, but a do-it-yourself fix is available The Linux kernel scheduler has deficiencies that prevent a ...

The current Completely Fair Scheduler (CFS) is also likely going to be replaced in the Linux kernel with the EEVDF scheduler as the default.

In order to eek out as much performance from Linux servers as possible, learn how to change your I/O scheduler to meet your needs.

A number of modifications were made to the general-purpose Linux kernel to make Linux a viable choice for real time, such as the scheduler, interrupt handling, locking mechanism and so on.
