I retested with UFS rather than ZFS.
The freebsd-update install after reboot gone from 42m49s with ZFS to 5m39s with UFS.

More details:
-the 44 patch update for 13.2 took 29s for the update phase, 34s for the install phase.

/usr/bin/time -h freebsd-update -r 14.0-BETA1
10750 patchs, 1309 files
17m42s, 6m23s user, 3m10s sys (ZFS was a bit less than 20 mins)

first install (before reboot):
18s real, 7s user, 5s sys (ZFS was 35.4s real)

second install (after reboot):
5m39s real, 1m13s user, 1m3s sys (ZFS was 42m49s real, 1m20 user, 1m27 sys)

Time of UFS is about 13% of time of ZFS for the install phase of the upgrade from 13.2 to 14.0-BETA1.
