I have wondered that and looked, and on some desktop systems boot up
with a standard BIOS is something like the time LinuxBIOS takes.  But
for server systems, and other lower volume systems I suspect someone
just does a lousy job.

Beyond that.  The easy things to mess up are things like the MTRRs.
If they are not turned on at the appropriate time you can easily get
a 10x slowdown.
