Sorry, you already said that -- 650k rows for one of them. If that table
doesn't fit in the cache on your Mac, you pretty much lose. From the EXPLAIN
output, it looks like it fits very nicely in cache on your server. Thus, I
don't think the difference is between 8.0 and 8.2, but rather your production
server and your test machine.
