While I don't want to proliferate this thread or advocate any kind of change, I want to address the sentiment that time spent in rc during boot is small or insignificant relative to the kernel time. The last time concurrent rc patches where proposed I measured boot time on my laptop (running 8.2-RELEASE i386 IIRC): out of 45 seconds from power on to login prompt, 20-25 where spent in rc, and parallel execution of it shaved off 7 seconds from boot time. I'm also seeing similar breakdown on VirtualBox: rc subsystem consistently takes about 40-50% of boot time. This is on a system with a static IP and where only sshd is started (even sendmail is disabled). _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
