[How to optimise Julia code: A practical guide](https://viralinstruction.com/posts/optimise/#) mentions some good tools from the Julia ecosystem related to performance optimization (some parts of it may be too advanced though, so feel free to skip sections and come back to them later). And the [Julia Notes](https://m3g.github.io/JuliaNotes.jl/stable/) page explains some of the stuff mentioned there in a bit more detail, for eg. sections on [type stability](https://m3g.github.io/JuliaNotes.jl/stable/instability/), [allocations](https://m3g.github.io/JuliaNotes.jl/stable/memory/), etc.
