Hi!

I find the [julia performance tips page](https://docs.julialang.org/en/v1/manual/performance-tips/) very useful. I am wondering if there is a similar document with some tips in order to reduce compiler latency and start up times. E.g., which patterns to use, which to avoid, etc.

Thanks for helping!

I provided some other good discussions below that you should check out @fverdugo. Also here’s a good blog post talking about [Composable multi-threaded parallelism in Julia](https://julialang.org/blog/2019/07/multithreading) if you’re interested. 🙂
