That k is an argument of the function (the function finds the k colors that are most similar to a given color). Each reported figure is an average of ten executions. I have not reported (and not computed) confidence intervals, so 11–15x may just be within noise limits. Interestingly, I ran those benchmarks on a version of Vim compiled by myself. If I use my system's Vim I get better results: k | Legacy Vim script | Vim 9 script ---|-------------------|------------- 1 | 33.1 ms | 4.0 ms 10 | 283.9 ms | 20.7 ms 20 | 512.8 ms | 51.0 ms The gap narrows a bit: Vim 9 script is 8–10x faster. Still quite a lot. Now, I have to find out how to optimize my custom build... Life. -- -- You received this message from the "vim_use" maillist. Do not top-post!
