After on-disk caching, the biggest performance improvements I've seen to compilers have been from changing how data structures are allocated/deallocated and laid out in memory. I haven't seen much opportunity to improve algorithm performance because which algorithms are applicable is heavily constrained by language design. In my experience the difference between something like Zig and a language with managed memory is large.
