Yes, for 4-word texts the results are similar.
Try that with a longer text and the difference becomes more and more significant. For the lorem ipsum text, 'polish' is about 4 times slower, than 'english'. For 5 repetitions of the text, it's 6 times, for 10 repetitions - 7.5 times...

Again, I see nothing unclear here, since dictionaries (as specified
in configuration) apply to ALL words in document. The more words in document, the more overhead.

You're missing the point. I'm not surprised that the function takes more time for larger input texts - that's obvious. The thing is, the computation times rise more steeply when the Polish config is used. Steeply enough, that the difference between the Polish and English configs becomes enormous in practical cases.

Now this may be expected behaviour, but since I don't know if it is, I posted to the mailing lists to find out. If you're saying this is ok and there's nothing to fix here, then there's nothing more to discuss and we may consider the thread closed.
If not, ts_headline deserves a closer look.

cheers,
