WPT + Show Slow

Does anyone have experience installing private instances of both WPT and Show Slow? I’m curious about the architecture(s) for these instances and whether it was better to keep them on separate machines.

I’m currently adding Show Slow on top of a functional WPT instance on a Windows VM without much luck.

Ask @hsiboy on Twitter (can’t remember what his ID is here) but he runs private WPT and Show Slow instances at laterooms.com
