instant drawing of virtual terminal

["hasan ali" <hasan.ali.3739@googlemail.com>]

How can I make new screenfulls of text get drawn instantly in a virtual console, rather than having to wait for the text to scroll up. For example when paging with less, I have to wait for the entire screen to scroll up until I can read the new text, and this takes a long time when my cpu is under heavy load. Thank You.
