Could be, but the problem appeared suddenly, on a mac that previously worked fine.

Actually, I was able to narrow down the time the problem started. It started after August 2017, and before September 2018. Don’t remember the current versions of MacOS or Elixir at that time.

No joy with the port install:
larry@habu ~ % time /opt/local/bin/elixir --version
Erlang/OTP 22 [erts-10.5.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] [dtrace]
Elixir 1.9.0 (compiled with Erlang/OTP 22)
/opt/local/bin/elixir --version 0.16s user 0.11s system 5% cpu 4.531 total

Works well for me on 10.14, so it looks like it’s an issue on your installation:
➜ ~ time elixir --version
Erlang/OTP 22 [erts-10.4.4] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [hipe]
Elixir 1.9.1 (compiled with Erlang/OTP 20)
elixir --version 0.42s user 0.29s system 164% cpu 0.431 total

That’s kind of what I thought, but I can’t figure out what it might be. As I said, I have the same problem on three different computers, and with a bare-bones test user on one of them.
One other oddity… Very rarely, I’ll notice normal performance for a few hours. Very rarely, as in once or twice a year. That said, because of the issue I haven’t been using Elixir very much.

I would try installing Erlang and Elixir using asdf as a previous commenter said. By doing that you could install older versions of Erlang and Elixir and switch between them to compare and see any differences.
I’ve noticed compile performance has improved in recent versions.
Performance is good on Mojave 10.14 with a slightly older Erlang (22.0.7) than you are using:
➜ ~ time elixir --version
Erlang/OTP 22 [erts-10.4.4] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [hipe]
Elixir 1.9.2 (compiled with Erlang/OTP 22)
elixir --version 0.46s user 0.31s system 147% cpu 0.516 total

I’m not a mac guy but on windows the usual culprit for sluggishness is antivirus software. Do you have anything similar installed?

Another possibility that comes to mind is if you have some odd filesystem. If you really want to dig into what’s happening you could look into DTrace. Although if I recall correctly you may need to disable SIP (which is a pain).

OK. I haven’t solved the problem, but I’ve isolated it.
I have a FireWire connected disk with a clean Mojave installation on it, set up with the idea of keeping some 32-bit games around. I booted from it, installed homebrew — which took forever — and the. Installed Elixir 1.9.2. No problem.
So the problem is with something on the other boot disks. All I have to do is figure out which files in that couple (or four) terabytes is causing the problem.
