No. ALV grid seems quite response.
it seem to be display of text.
ex)Transaction FBL5n can be display the output in Text and ALV.
ALV works well. Each scroll down moves the screen ( no hour glass is display).
When I output in text as shown on screenshot below ., every scroll down causes the hourglass to appear and it takes 1 to 2 seconds before it scrolls a single line
