In single user-mode (nvram 'boot-args= -s'), the null syscall latency remains about the same. The ioctl latency actually does drop a tiny bit to a little more than 2.40us. I forgot the copy the SimleUserClient kext to a local disk, so I did not test that.. I first entered single user mode via kill -TERM init. This led to a doubling of the null and ioctl latencies. Its not important at all, but I'm curious why this was. Some problem caused by mach_init going away?
