If you’re running lots of cores hard or doing "Big Data”, this paper is of interest.

The Linux Scheduler: a Decade of Wasted Cores

> In our experiments, these performance bugs caused many-fold (a 138x corner case) performance degradation for synchronization-heavy scientific applications, 13% higher latency for kernel make, and a 14- 23% decrease in TPC-H throughput for a widely used commercial database.
