+Compile times (full and incremental) are one of Rust's pain points.
+[Azriel] published a devlog about optimizing [Will]'s build times.
+Summary:
 
-**TODO**: img?
+> In a 45k LOC / 102-crate workspace,
+> moving tests from member crates into a single workspace_tests crate
+> achieved the following improvements:
+>
+> - Build and test duration in release mode reduced
+>   from 23 minutes to 13 minutes.
+> - Debug artifact disk usage reduced from 20 G to 7 G
+>   (65% reduction, fresh build),
+>   or 230 G to 50 G (78% reduction, ongoing development).
