I've found this thread to be fairly interesting, but am not seeing any
of the slowness that has been talked about.
I should probably have provided some benchmarking code that people could
check for themselves -- but the project in which my benchmarking evolved
did a lot of other stuff, and it wasn't easy to isolate...
But now I have put together a simple TableView with 500 rows and 2
columns.
The program will setup a timer to call the scroll method 60 times pr.
second. Every 25th invocation will measure the time since last, and
based on this calculate a frames pr. second count.
So just run the program and enable "scroll programatically", then you'll
see a fps which should be close to 60. Now try to make the window larger
and see how it drops -- on my system it drops to 17-18 fps when the
window fills my entire desktop (which runs at 1600x1024).

Have fun...
