Combined with Ken's suggestion to use "difference", looking up a list
of about 50 words in the filtered dictionary reduces the time from 2-4
seconds to about 40 ms. It varies, depending on a lot of things, but
it's fast enough that you don't notice. That's on my Pixel 5; on the
Mac a lookup takes 5ms. And I can do it all in LC script.
5ms !?!
I did a (very simple) test (see code below)
- take the whole sowpods.txt file (267k words)
- create a set (i.e. split by CR as set)
- look up 50 randomly chosen words + 5 non-words (just in case failed
searches were expensive).
Doing this 100 times takes 6-10 ms (on an old MacBook Pro).
Could you maybe post the code that you're using that takes 5ms ?
I love these little speed contests we have here. Thank you.
