For me Dolphin gives a count of the items within the subfolder, not recursively
down into the whole tree. I do get a recursive count if I right click on the
"bigfolder" and look at properties.

Nevertheless...

Might be worth holding out until you can test with the Paragon NTFS drivers
(rather than NTFS-3G). My experience with Fedora 35, as per

    https://bugs.kde.org/show_bug.cgi?id=406506#c21

was pretty good. I tried your test script on F35 (100 folders, each with 100
empty files) in an NTFS partition and Dolphin was OK.

1000 folders, each with 1000 empty files, was a bit more of a challenge.
Dolphin was OK but you could see that baloo was fighting to catch up (it needed
an hour to note down the newly created files - although if you say 250 per
second that doesn't sound so bad). That clearly had an impact on the system.
Once the baloo_file had caught up with the new files and started to schedule
the content indexing the impact was far less.
