Same thing on my VPS
I recently signed up for a VPS with CentOS and CPanel/WHM. The exact same thing is happening on mine. Spikes every hour, on the hour. They last about 4 minutes and during that time there is piss poor system performance.
High IO Wait time. Memory levels are fine. No RAM swapping.
I monitored top during these spikes and the process that kept floating to the top was: md5sum
