painintheworld I ran the test program on my RPi400 running EB LT. It was almost instantaneous at 0.043 Seconds everytime. I'd say the RPi400 passes the test.
BTW, got a new notebook computer at Micro Center on Sunday. It's an Evolve III Maestro E-Book 4+64 with a 4-Core Celeron N3450 running Win10Pro Educational. It was $80+tax but I bought new open box (cardboard flap torn) and got it for $69.10 out the door. I may try the X64 version on it if I can get it to boot from thumbdrive or uSD.
Now to try my other EB programs on the RPi400...
