At some point, the community is also responsible for the demanding expectation of a "not slow" compiler.

What's "slow"? What's "fast"? It depends. It depends on the program, the programmer, his or her hardware, the day of the week, the hour of the day, the season, what he or she had for lunch, ...

It's a never ending quest.

I, for exemple, am perfectly happy with the current benchmark of the rust compiler. I find a x2 improvement absolutly excellent.
