> Julia seems to have gotten about [4x faster on master](https://discourse.julialang.org/t/topological-sort-performance/17153/29), so probably it is now about 4x faster than Python on the Pythonic version of the algorithm.

That was from the timing in [Performance problem of count? - #13 by Sukera](https://discourse.julialang.org/t/performance-problem-of-count/16873/13) which was linked from [Topological sort (performance) - #18 by Liso](https://discourse.julialang.org/t/topological-sort-performance/17153/18).
