A good way to track down performance issues like this is to use @code_typed to output the typed code in your function and look for places where type inference doesn't know what to do; e.g. large type unions, Any types, etc.... This is often caused by a variable taking on multiple separate types over its lifetime within the function and can cause slowdowns inside inner loops. -E
