[image] Dan: I think there are many times a Dict is known to have keys from a small universe, and speed is paramount. Go implementation seems to do this (using the knowledge that there are max 100 tags). The Dictionaries.jl supports a size hint, but in the current scenario, seems slower than…

If I understand correctly, that finds the topn largest values in a list ? (edit: index of the ntop largest values) If so, you might look into this [image] Find n smallest values in an n dims array New to Julia Thanks guys. This should be included somewhere in Julia

we need the index of topn largest values in a list, which is precise partialsortperm( ;rev=true), but it’s much slower

That is then exactly (?) what was discussed [image] Find n smallest values in an n dims array New to Julia Thanks guys. This should be included somewhere in Julia but for the minimum.

[image] jling: partialsortperm sortperm and friends are really slow in Julia sortperm has poor performance · Issue #939 · JuliaLang/julia · GitHub Also, partialsort dispatches between partial-scratch-quicksort (good for long inputs) and insertionsort of the whole input (good for short inputs…

Current results: [image] The underlying data (used for the leaderboard) is changing from run to run, and it seems to affect the results regardless of underlying implementations. For example, Zig was not updated in 4 days and jumped on top for the current run (the same implementation a day back d…

this function has the funny property that if I add @inbounds it actually becomes slower (given we’re using MVector now)
