Table behavior with scroll very slow

Hi friends,
I’ve a table inside a panel with many rows (more or less 5000 rows) that when I try to move registers with scrollbar behaves very slowly but when i use the arroy or pag forward, pag reg works fine…

Any idea? What It could be?

Have you tried playing with the cacheRate on the table?

See

. Setting the cache rate to 1 or 0 may give you better performance…
