3X speedup is a definite improvement. I don't use rust regularly, so have been relying on community news for updates and while they have mentioned planned work to increase compilation speed a few times they haven't really talked about any landing (that I saw anyways). Also cold start speed is not really what I care about. I am more concerned with compiler speed while working and running tests. I find that if a language compiler is to slow it breaks flow while testing changes. I haven't seen much mention of the improvements the incremental compiler gives in a while. Last I read was the 2017 blog post [1] during beta and it only showed modest improvements and more recently I only see talk of how it still needs a lot of work [2].
