Hi,

I wanted to see if my CFLAGS (in mk.conf) were of any use.
So I compiled security/openssh and did a few ssh-keygen:
# clear; while [ true ]; do time
/usr/pkgsrc/security/openssh/work/openssh-4.3p1/ssh-keygen -t rsa -f
/tmp/null.key -N '' > /dev/null ; rm /tmp/null* && sync ; sleep 300; done

With CFLAGS set (-mcpu=ultrasparc -mtune=ultrasparc -m64 -mvis -pipe)
   17.45s real    17.39s user     0.03s system
   40.93s real    40.90s user     0.00s system
   14.71s real    14.70s user     0.02s system
    8.69s real     8.69s user     0.02s system
    6.02s real     6.02s user     0.00s system
   23.71s real    23.66s user     0.03s system

Without any CFLAGS set (no /etc/mk.conf at all), I got those results
   50.80s real    50.75s user     0.01s system
   43.97s real    43.94s user     0.01s system
   31.94s real    31.90s user     0.01s system
    7.05s real     7.04s user     0.02s system
   26.44s real    26.41s user     0.03s system
   20.99s real    20.96s user     0.02s system

what surprises me the most is the various values I get.
when I did some "dd" testing to check disk access, results were quite the
same inside a test set.

the machine IDLEs when not ssh-keygen(ing).

it's an U10 with 512Mo of RAM, running on it's default IDE drive and
running NetBSD 3.0-RELEASE (gcc 3.3.3).

here's a few things I wonder:
1. why results aren't closer (inside a test set)?
2. what's best (for a productive server), more time in "user" and less in
"system" (no CFLAGS) or the contrary (CFLAGS set) ?
3. is this test good enough to be run on -CURRENT and check gcc 4 value ?

TIA,
     Jo
