The loop takes forever. Here it is (sDictFile is a script local):

  repeat for each line l in pList -- pList is the user word list
    if sDictFile[l] = true then put l & cr after tCheckedList
    else put l & cr after tNonWords
    wait 0 with messages  -- prevent ANRs
  end repeat

I added the wait because my Android phone was putting up an "app not
responding" warning while the loop was running (or just after, hard to
tell.) The loop should be much faster than that. When I added some
timing checks though, the timer says the loop takes between 0 and 1
millisecond, and yet the wait on screen remains.

If the difference between `the milliseconds` before the loop, and then after is 0 or 1 millisecond - then that is how long it is taking. This means the issue is somewhere else. Are you sure there isn't anything you are doing either before that loop or after that loop which doesn't wait for ages (due to the ANRs you mentioned).

With a 3-word user list, the loop takes 4 seconds. With an 8 word user
list the loop takes 6 seconds. The more user words, the longer the
wait.

If there are only 3 reasonable length words in pList (I.e. 3 lines) then there's no way that loop can take 4 seconds. Of course if the words are multiple megabytes long then it might be possible (however the timing you already stated above suggests the loop isn't actually taking 4 seconds!).

Even stranger: on my cheapo Android tablet with 4 megs of RAM running
Android 9 the response is nearly instantaneous, even if the user list
has 200+ words. On my Pixel phone with 8 megs of RAM and Android 12
the response is slow enough to trigger the ANR with only 3 words. I'm
building for ARM 64.

This strongly suggests it is something else either on your phone, or in your code which your phone doesn't like I think.

Warmst Regards,

Mark.
