Introduction

This post discusses the performance of Linux context switches under the Xen hypervisor. Presence of the Xen hypervisor has an impact on the context switching performance, as is shown by benchmarks. I was interested in these benchmarks since I had the feeling a Xen-enabled machine is in general running slower than a non-Xen machine.
