Hi all, I have a relatively big simulation function (which has 20,000 repeated loops). The @time results show more than 64.5G allocations. Are there some tips to reduce the allocations? Thank you in advance.

See Performance Tips · The Julia Language . Specifically, check for type instability and slicing as the two most likely.

Thank you very much for the advice!

This is helpful, thank you very much @lmiq

In my simulation https://github.com/ufechner7/KiteModels.jl/blob/main/src/KPS4.jl I have zero allocation. Line 386ff, is the main callback function. function residual!(res, yd, y::MVector{S, SimFloat}, s::KPS4, time) where S I use this struct @with_kw mutable struct KPS4{S, T, P, Q, SP} <: Abstra…

Thank you very much @ufechner7 , going to check your code.
