App speed matters some. But not nearly as much as a lot of other things. And when speed is the biggest problem, your users can tell you and the fixes are pretty straightforward.
The hard things to solve require a lot of user-facing iteration. Basically, the faster you can try new things, the more likely you'll get product-market fit before you run out of money.
My feelings on Rails are decidedly mixed, but fast prototyping is one of the things they got right.
