Most of the increase in build time is new Rust code, and icecream doesn't distribute Rust. So in addition to some long compile times for final crates limiting the minimum build time, icecream doesn't help much in the run-up either. This is why I'm excited about the distributed build feature we're adding to sccache. I'd still expect some improvement from the C++ compilation though. > It’s a very sweet machine indeed > Glad you finally got one! :) -r _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
