When I was using an RPi2 for VAX emulation, I showed as having about 1.6 VUPS under OpenVMS 7.3.  I’ve since moved to a VMware cluster for my VAX emulation needs.  It can beat my fastest VAX.  

I use RPi3’s for PDP-10 and DPS-8 emulation, I haven’t tried them for VAX emulation.  I would like to try a RPi4 for VAX emulation.
