Since osdteletext page drawing is rather slow on my C3-600, I investigated the page rendering speed of osdteletext-0.4.2. After a rewrite of the scaler, the scaling is down to 0.1s, speeding up screen update from 0.74s to 0.39s - a noticeable improvement. ;)
Time to heat things up!
The new patch replaces almost the complete character rendering, and draws directly to the osd display buffers. Render time is now down to 0.172s, giving a speed boost of 4.3x. :)

On a side note - Displaying the current page again only needs 0.08s, I guess this is due to reading from same disk buffers again.
Cheers,
