Switch to baselayout-2 and openrc..the speed up is noticeable. Especially if you enable
rc_parallel="YES" in /etc/rc.conf. Anyway, others have wrote about it already, including a bootchartd of before and after here.
Anyway, this should be hitting stable soonish and when it does be sure to read the migration guide because some things have indeed changed.
For me, I count to 10 slowly and my laptop is at the xdm prompt…very cool and good job Roy!
