alt Hacker NewsAda’s failure to escape its niche is overdetermined.
Given the sophistication of the language and the compiler technology of the day, there was no way Ada was going to run well on 1980’s microcomputers. Intel built the i432 “mainframe on a chip” with a bunch of Ada concepts baked into the hardware for performance, and it was still as slow as a dog.
And as we now know, microcomputers later ate the world, carrying along their C and assembly legacy for the better part of two decades, until they got fast enough and compiler technology got good enough that richer languages were plausible.

I sometimes wonder what "Turbo Ada" would have looked like, but I think it would have probably looked like later versions of Borland Pascal. Things like generics and exceptions would have taken some of the "turbo" out of the compiler and runtime -- the code generator didn't even get a non-peephole optimizer until 32-bit Delphi, it would have been too slow.
It might be nice to have Ada's tasks driven by DOS interrupts, though. I think GNAT did this.
I used it a bit a Uni and remember enjoying it, but can you say what was slow about it; compilation or runtime or all of it?
The first validated compiler for Ada that ran on the IBM PC was released in 1983.
The third validated compiler ran on the Western Digital “Pascal MicroEngine” running the UCSD p-system with 64K memory. The MicroEngine executed the byte code from the p-system natively, which was an interesting approach.
I think more research is warranted by you on this subject.
