Unfortunately I suspect we both can't really and shouldn't do anything here. A non optimized build is going to be too slow for any meaningful work. I believe there are similar pre-existing issues for the general case of this bug, though I don't recall if they have any resolution.

Then should we just get rid of this option in
config.toml? if it's exposed, it's supposed to be working...Mark-Simulacrum commentedon Oct 13, 2019
You're probably not wrong, it's mostly that no one has gotten around to doing so.

I'll check if it's easy to create a patch to remove this.
