That has not been my experience, I am seeing severe performance problems
with a table that gets reloaded on average about once per second
(displaying players in an online game). In my case, I see a substantial
difference when the table fills about half the screen size (say 800 x
600 pixels) versus a smaller size (300 x 100), indicating table
redrawing is a bottleneck (the table has 125 rows x 10 columns, 5
columns display NSImages). At the bigger sizes, it completely swamps the
CPU (400 mHz PB).
