Could the CPU be reducing its clock rate when it's not being loaded? Just
a guess, most multi-core processors these days have power saving features
like that.

Setting /sys/devices/system/cpu/cpuX/cpufreq/scaling_governor to
"performance" should lock that core to the max clock rate.
In looking that up, I found that the script I made to set this was just
doing cpu0 (i.e. one of four cores). Doh! I've changed it to do all 4
cores, and am trying that again to see if that's it.
