Hi! I have some functions in a loop that get called a huge number of times. Some of them have two different forms, one when my elements are triangles and on when they are quads. Normally, I’d write two different for loops, check if I have quads or tris before entering the for loop, and then call th…

This depends on what your data is. If you are dealing with something like a Vector{Quad} or Vector{Tri}, than multiple dispatch is zero cost. If you have a Vector{Union{Tri,Quad}}, then Julia will probably just put an if statement in. If you have a Vector{Shape} (where Quad, Tri are subtypes of shap…

Any performance issues with multiple dispatch?

You will reach a performance penalty if the number of types increase, which can be dealt with manual splitting. There are some threads discussing that, and solutions, for example:
