I just measured the time taken by the boot animation by the simple technique of renaming /usr/bin/rhgb-client so the initscripts can't find it.
With boot animation, OS build 7 (an older 8.2.1 candidate) takes 60 seconds from first dot (indicating OFW transfer to Linux) to Sugar "prompt for your name". Without it, 53 seconds. I repeated the test several times with consistent results. Clearly, it should be possible to display that amount of information in much less than 7 seconds. The boot animation code is in the OLPC domain, not the upstream domain, so replacing it should be relatively free of upstream politics. So if anybody is interested in implementing a relatively simple boot-time speedup, I offer this as low-hanging fruit. I suggest 1 second (differential time between animation and no-animation cases) as a reasonable target goal, assuming images of the complexity of the current ones. Arbitrary full-screen graphics might require more time, but speeding up the baseline case is a good starting point. Go wild. _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
