Thanks, Richard! Yes, if you're not on the list for that bug, that would
superb to sign up. I thought it might be considered old or familiar news
here since tests and observations had been posted and discussed before
by myself and others, so at first I didn't want to sp*m too much info
again. Here we go in reverse chronology:
Jan 2019: Current mention, as a reminder and still-the-same 902 status
Sep 2018: LC Version "Showdown" video with several tests between 6.7 and
9, to accompany separate Bug Report and Test Stack. (3 Links.)
2018: Several list discussions that touched on performance. Including
your JS speed comparison suggestion, which I included. Also Mark's note
about array work, and some array vs list tests by others.
Jan 2017: LC "Fight Night" video with demo tests between LC 6.7, 5.5,
8.1.2 and 9 dp 4. At that point 9 was still very much under
construction, so 8 was the stable data point. Didn't have a chance to
post followups that year.
Prior: As I recall, I noticed performance differences from LC 7/8 on and
mentioned it, but heard back officially that the new LC would go through
an optimization stage, so I waited accordingly.
Of course all this may NOT cover all performance issues; it's a limited
set of tests as examples.

True enough; I've mentioned my own rule of refraining from speculating
much on the causes, but pointing out the areas affected, and countering
a just-Unicode-as-expected meme that pops up now and then. The "Fight
Night" was designed to pin down what I had encountered in my own work -
that several areas were affected, not just text and arrays. Some tests
were designed to avoid type coercions to the extent possible. (I think
it was especially "Root Loops" - the original version, not the big calc
variation.) So I can't say for sure that it's not happening, but in
those cases it shouldn't be.
Hope you enjoyed the R^3 link antimeme joke! :) Miss our periodic
catch-up calls; maybe we can do one later this year when we have a chance.
