Bug#430542: debian-installer: screen updates painfully slow on serial console
Package: debian-installer
Severity: wishlist
I'm installing etch on a sparc system through serial console. Sun
machines apparently use 9600 baud on the serial port. The screen
update method of the installer makes this process really slow.
The screen is drawn about three times for each new page. First the
background is filled, then the dialog box is drawn on top of that, and
finally the whole thing is erased with a third pass when the dialog is
finished.
The screen blanking and background drawing are really unnecessary, it
should be possible to optimize them away.
