the only suspicious USB-related thing that i noticed was the 1.6 seconds in the firmware, apparently to discover the wireless. in the normal boot case i wouldn't think we'd need this, but perhaps in the truly normal case (no dev key) we don't do it. i didn't re-run the test with no dev key. > On the software-side, sshd takes close to 3 secs to start, would make > sense to disable in user builds - without a password it is not useful > anyway. right. this is exactly the kind of thing this tool is good for spotting. just as scott wants to put a stake in the ground about not letting the next release get bigger, i think it would also be worth not letting it get slower. paul =--------------------- paul fox, [EMAIL PROTECTED] _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
