I might be mistaken, but the brief look at code shows that the speed up appears to come from combination of async architecture (the selling point of Mold) and intelligent usage of PUNCH_HOLE/INSERT_RANGE fallocate() operations.
Surprisingly enough PUNCH_HOLE and friends have already matured to be production ready, with viable support from ext4 and xfs filesystem. The possibilities!

I stand corrected! It would be interesting to try and use the Zig linker for something else, would be a neat weekend project.
