I do not mean just MT or Zorro performance, I mean mainly operative system performance, that also affects the overall computer performance. If the operative system runs faster, the apps run faster.

You can do the test:
create two t2.micro instances in AWS, free for 12 months. One of them with Windows + MT and the other one Ubuntu + MT. Which one can you work better?

I am running several Ubuntu machines with MT4/MT5 with and without Zorro since few days ago. Zero problems so far, they keep running and trading 24h/day.
