The elapsed time seems correct on both systems. However, the
proportion of user to system time is more or less reversed and quite
wrong for the dual-processor system.
Any ideas?
The CPU's are spinning in kernel mode on the master kernel lock we
have for SMP. Userland is of course multi threaded on SMP, but the
kernel is simgle threaded so all those faults being done by your test
program must be processed serially.
