Open Source Summit Europe + ELC Europe 2017

The Real-Time Patch (also called Preempt-RT) allows for soft real-time performances using the Linux kernel. It is getting easier to find some good documentation on fine-tuning and benchmarking the real-time capabilities of a system. When applying the Preempt-RT patch, you should also consider the non real-time related impacts on a system. In this talk, Maxime will present the different performance improvements and deteriorations that you can expect when using the Preempt-RT patch, based on real-life use cases. This will be the occasion to dig into the Preempt-RT patch to see why some aspects of the system behave differently, focusing on raw computing, network, and I/O performances. Maxime will also give some feedback from a developer standpoint on what it means to maintain a BSP that uses the RT-Patch.
