I took a look at it and that's an interesting project, albeit 
somewhat unpolished. It wasn't exactly clear what's the 
difference between "Check Time", "Compile Time" and "Build Time" 
from their readme until I checked the sources. Also the table is 
unsorted ("Sort table primarily by build time and then check 
time" in still in their TODO list). The difference is that they 
are generating a large source file with a lot of functions and 
calls between them to test how fast a compiler can process it. 
While here in this thread we are primarily looking at a different 
use case: a smallish program, which imports somewhat largish 
standard libraries.

Still enabling PGO for the downloadable DMD compiler binary 
releases is going to also improve nordlow's benchmark results. 
And using `mold` as a faster linker would help them too.
