I upgraded my website recently and it's exciting! That being said, I admit my builds didn't get faster (they actually on average slowed down a bit). Hopefully that improves, but worth noting.
I have used MonoLisa for more than 6 years now (I was one of the first early users!) and it's still my favorite font to this day! It's the best. I particularly like how wide it is for teaching and sharing screens. It's really legible and nice!
