Avoiding runtime dispatch is perhaps the #1 optimization advice in Julia forums. As I understand it, the reason is that when the Julia compiler does a runtime dispatch it does not at compile-time neccesarily know the return type of the function to be called. And so, it needs to allocate space for t…

Note that there’s an escape hatch for changing max_methods if the code requires: julia/base/experimental.jl at 96866cb8f5c8f28d96c2b9e4eb1ec4f3a00a705b · JuliaLang/julia · GitHub
