Make sure your system is idle. Userspace bloat means that *lots* of idle
activity occurs in between timer ticks on recent distributions -- all those
widgets polling the hardware to see if something changed or needs updating
do a lot of damage to the caches. Try comparing a run under init=/bin/bash
with one while logged in to a desktop environment to see just how painful it
is.
