Yes, at least on the initial load (before caching everything). On subsequent loads it would take at least 20-30 seconds to start.
How does it look without LOCKDEBUG?
I would have to build a new kernel and check. Do you thing it is truly relevant? Would there be a lot of locking/contention occurring during the program start-up phase?
FWIW, someone also suggested that the "3-seconds needed to unmount a nullfs" problem could also be affected by LOCKDEBUG. Interestingly, this problem does not seem to persist. Some time after the system is booted, and some time after all the nullfs mounts are completed, the unmount process completes as expected; all 20+ umount complete within total of 3-4 seconds, rather than 3-6 seconds each. I'll try to characterize the "some time after" details later, after resolving the bigger outstanding issues.
