[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 ...

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.

Future releases of Linux may provide more responsive desktop performance thanks to a new "completely fair scheduler" being incorporated into the mainline Linux kernel.
