I ran

../../../build-support/bin/native/cargo build --release -p engine

(7m19) and then

../../../build-support/bin/native/cargo build --release -p fs_util

which took 1m03. Looks like about 41 seconds of that was building dependencies (mostly clap, the command line parser, which should be entirely cached if we’re caching the

target

directory), and 22s was compiling and linking the actual binary.
