I happened to try running
time make all-depends-list
ten times in a row in /usr/ports/x11/gnome2. The system was freshly
booted, and other than a niced setiathome, the system was idle. I got
the following results:
122.63 real 29.83 user 66.29 sys
117.86 real 29.58 user 66.55 sys
119.89 real 29.80 user 67.27 sys
121.68 real 30.31 user 67.55 sys
122.10 real 30.41 user 67.66 sys
120.90 real 29.67 user 68.24 sys
121.21 real 30.27 user 67.69 sys
219.85 real 30.35 user 148.12 sys
312.54 real 30.49 user 224.79 sys
312.83 real 30.23 user 225.83 sys
The last three lines are rather strange ...
Kernel and world are 6.0-CURRENT, built from February 3rd sources.
WITNESS, INVARIANTS, DEBUG_VFS_LOCKS, and SMP enabled, and it is fairly
close to GENERIC.
Here's dmesg.boot:
