Description of problem: When I install and have the output use the serial port for console (console=ttyS0,9600) the install slows cause its trying to display all the screen changes during the package installation dialog. When I do the same install without serial console , it finishes the install several times faster. Is there a way to decrease the amount of screen redraws/changes when doing a serial console install? I would increase the baudrate but it is not an option I have. Version-Release number of selected component (if applicable): How reproducible: Notice the difference for every install I do. Steps to Reproduce: Setup console redirection with console=ttyS0,9600 start the installation
I guess you can use "cmdline" instead of "text" installation?
I still see the same thing.
The reason that the installation is slow is because of the 9600 in the console command. If you increase the baud rate anaconda draws the screens much faster (if you use 19200 its not even noticeable). AFAIK, its not that anaconda isn't quick about painting the screens, its that anaconda receives the info at a slow rate. Try 4800 and it will be slower :)
