It has improved significantly since the early days of 3.0. Not back to 1.1.1 levels of performance, but enough that it's probably not a dealbreaker for most people.
To put that in perspective: I noticed that private key parsing was 70 times slower in early 3.x versions. I think it's only 8 times slower in current versions. That's still... a lot slower. For no good reason.
