There is no way to patch out Mix.Utils to run your own code. The proper fix
would be to figure out why the path traversal is slow on Elixir (it is
implemented on top of filelib:wildcard) so we can fix it rather
permanently. How long does "Path.wildcard("lib/**/*.ex")" take? Can you
implement your own path traversal in Elixir? Is it faster than
Path.wildcard?*José Valim* www.plataformatec.com.br Skype: jv.ptec Founder and Director of R&D On Mon, Oct 14, 2019 at 8:08 PM Michael St Clair <[email protected]> wrote: > I've been doing some digging around to see how to make phoenix run faster > in Docker.
