Mix compile timeout warning - should I be concerned?

[OTP, erts, mix 1.10.3]

When running mix compile, I see many warnings like this:

Compiling lib/foo/bar/file.ex (it’s taking more than 15s)

Is there a config parameter to increase the 15s value?

These are not timeouts, it’s just letting you know that it’s progressing even though the compiling takes a long time. These are normal and there is no reason to disable them.
