> (You could do the same with `@sync` and `@spawn`, but there would be no advantage here. To improve load balancing you can simply increase the number of chunks (or use the `:scatter` chunking option if there is a correlation between the index of the task and its cost)

Note that `@threads` (or, explicitly, `@threads :dynamic`) isn’t the same as `@sync @spawn`. In particular, perhaps contrary to intuition, the former does **not** implement proper load balancing whereas the latter does. Check out my comment [here](https://discourse.julialang.org/t/multi-threading-appears-to-be-single-thread-when-some-threads-cost-much-more-time-than-the-others/101353/16).
