05/10/2023, 5:53 PMOk... well we wrote that off years ago. Pants simply doesn't work without pantsd almost by design.

05/10/2023, 5:53 PMbut if the JIT can’t get warmed up in 80s, it’s not going to be helpful here.

05/10/2023, 5:55 PMi expect that it would be worth it to begin reimplementing the innermost non-plugin/core objects and rules in Rust.

05/10/2023, 5:55 PMwe’ve done it piecemeal, but not in a concerted way. and i think that doing it in a concerted way could make a significant difference.
