The article is quite weak IMO and mixes up a few things. For example, there isn't really a "global allocator" built into the C language. In the case of your quote, this is a misunderstanding on the performance optimizations that were done on the Zig compiler itself (it compiles faster). But that makes no difference to the performance of the compiled program. And the techniques that were mentioned can be used in the implementation of any other compiler as well.
