I installed FreeBSD 10.3 on brand new machine Supermicro X11SSW-F. It sits on top of 4x 1TB Samsung SSDs on ZFS RAIDZ2. The booting is painfully slow from BTX to menu to kernel loading. Progress indicated by \ | / - characters is changing by speed of 1 character per 2 seconds. The whole boot process takes about 10 minutes. I found this blog post solving the same problem http://smyck.net/2016/06/15/freebsd-slow-zfs-bootloader/ It seems there is some bug in loader in 10.3. If /boot/pmbr, /boot/gptzfsboot and /boot/zfsloader are replaced by files from 11-CURRENT snapshot (from ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/amd64/11.0-CURRENT/base.txz) the booting speed is back to normal. Is it know problem? What was changed in loader between 10.3 and 11? Miroslav Lachmanhome | help
