I tried another buildworld buildkernel (self rebuild)
after the recent UFS SU related file system performance
fixes:

World build completed on Thu Mar 11 18:39:37 PST 2021
World built in 29780 seconds, ncpu: 4, make -j4
Kernel build for GENERIC-NODBG completed on Thu Mar 11 19:18:02 PST 2021
Kernel(s)  GENERIC-NODBG built in 2305 seconds, ncpu: 4, make -j4

So a few minutes under 9 hours, a little more time than
my prior report.

This was based on main c328f64d8107 and otherwise similar
conditions. For reference:
