I have the same problem on a Supermicro X11SSH-LN4F.

I'll test that solution. Thanks for the pointer!
Tested, works -- I took the 12.0-CURRENT boot files:
gpart bootcode -b pmbr ada0
gpart -p gptzfsboot -i 1 ada0
cp zfsloader /boot/zfsloader
Before: ca. 660 seconds to reboot, now 77 seconds to reboot.
Now, if someone could explain, why...
there were some buffering changes and other stuff in the boot
blocks/loader.
