groupadd, useradd, etc

[Bill Gradwohl]

More info:

Heres a top immediately before a groupadd command:

Heres the top while groupadd is running, about 30 seconds into it:
top - 20:25:33 up 1 day,  3:26,  3 users,  load average: 1.19, 1.24, 1.25

Here's the time output:
root at s2 ~# time groupadd docers

real    3m21.632s
user    0m27.710s
sys     0m9.414s


All of the group* and user* utilities take roughly 3 1/4 minutes to 
complete. The only users loged in are my ssh session. Check out the 
memory used during the groupadd. This is on a new P4 @ 2.6ghz

Everything else on the box appears to be normal.
