Hi,
2 computers with 2 accounts is fine but, according to your stated concern, won't you need 2 internet connections to totally optimise them?
I use one computer for MFPRO and another to stream the Betfair video. It works very well. But my triggers are not just speed driven, in fact if they were I would have no hope for them. Even if I had the ultimate internet provider, I won't get matched all time and I'm not even relying on the current next-trade available amounts.
If you really need so much speed then 2 computers and 1 account is the way to go imo. Reduce your open markets as much as you can, perhaps one market open on each at any time and trim back the settings eg not loading all prices, not logging triggers, not opening browsers etc
Good Luck
