FreeBSD used to take forever to boot on certain low-end ARM CPUs with /etc/rc.d after it was imported from NetBSD. This was due to crappy root-device performance (100kB/s is enough for anybody, right?) and crappy, at the time, pmap code that caused excess page traffic in the /etc/rc.d environment. Perhaps those areas would be fruitful to profile? Also, there were some inefficiencies that were either the result of a botched port, or were basic to the system that got fixed. Between fixing all these things, the boot time went from 10 minutes down to ~20s. Warner
