I believe the odds are 3 to 5 that the lag will get so bad that you will not come back often over the next week.
But I'm not a betting man.

I don't really notice any speed issues. What browser are you using Ironwolf?
Chrome's been way faster than IE for me.
Fairly high. We'll probably have to turn some features off.
