 51e47481fc6f131d)` and I don't see a significant CPU usage increase
 compared to 0.3.0. It's true this relay's bottleneck is the bandwidth
 because it's capped, but there is no big difference in terms of CPU %
 usage per tor user / process as opposite to 0.3.0 - it's still around 9% -
 20% with very small period bursts to even 98%.
 > You should test with 0.3.1.x, according to Hello71 "KIST incidentally
 moderately improves CPU"

 I also experienced no noticeable increase in CPU usage with 0.3.1.7
 compared to 0.3.0.10, although I only ran it for a few hours and didn't
 precisely measure anything.
