add framebuffer set … to /boot/loader.rc.local

hm, that is interesting finding.

Thats just two samples, you need more to draw conclusions:)

Is it BIOS or UEFI setup? if bios, then all you need is to copy /boot/loader from older BE (beadm mount OLD /mnt; cp, then beadm umount). Just in case, make copy of existing one.

But, there are few things to keep in mind.

loader and kernel console draw are different things, the ls itself got some fixes recently.

So, is the performance degradation actually hitting only loader? 

Can you please mail me output from: tr '\0' '\n' < /system/boot/environment
