AFAIK if you have gptzfsboot on your drives it will probe the
partitions on your drives, which can take a while. So if you suspect
ZFS it might really be an option to replace gptzfsboot with gptboot.
I recently changed the configuration of my home server from 1x80GiB
SATA HDD (booting & /-pool) and 4x400GiB PATA HDD for zraid-Pool on
geli to 2x2TiB SATA HDD with gmirrored /boot and the rest for a geli
encrypted zmirror (including /). For me it feels as if it takes a few
seconds longer for the loader to appear. The latter uses GPT and
labels where possible.
