So, it seems like something is causing the performance of your system as a
whole to degrade at regular intervals.

Does top show any additional CPU load while performance is degraded? Or does
something like iotop or vmstat show I/O during those times?

Does it also affect pure CPU applications, e.g. audio or video encoding /
transcoding?
