I have a fs here with similar (but smaller size) parameters concerning
inode density and usage:
Filesystem 1K-blocks Used Avail Capacity iused ifree
/dev/ad1s1d 113390248 92926924 18195520 84% 248434 14424460
time mksnap_ffs'ing gives the following result:
0.007u 1.902s 1:51.94 1.6% 5+217k 4493+8646io 0pf+0w
It takes almost 2 minutes which seem to perform similarly to your 5
(There was not a single file opened when snapping.)
I'd expect snapping to speed up by reducing the inode number when doing
newfs, but I haven't verified this right now.
