Yes, that would be the best, but I'm wondering how, because e.g. "time
bzip2 -9 foobar" wouldn't be helpfull. So now I've switched to "-Os"
and soon I can test, if it's a real difference.


Please report back your findings, including the application mix you
tested.  Although "scientific" timed benchmarks are important, I would
also be interested in how the system feels.  For the latter ("feels"),
you should qualitatively describe the use of the system (web server,
desktop, laptop, etc) and what you commonly run (program devel, games,
scientific/engineering apps, etc).

Hi,

I've a desktop system and I commonly use applications like firefox, thunderbird and so on, kde, gaim and a terminal is nearly always there. Sometimes I'm running vim or kate.

If you're interested in some tests, not relevant for desktop systems, there are some I made:

Time wasted to compress a 416 mb tar:
        bzip2           gzip
-O3     2m40.882s       1m20.445s
-Os     2m39.314s       1m21.157s

decompress:
        bzip2           gzip
-O3     0m52.575s       0m4.972s
-Os     0m53.387s       0m4.828s

Convert 203 Mbs MP3s to WAV using LAME:
-O3     14m4.461s
-Os     16m50.599s

from wav to mp3:
-O3     1m1.708s
-Os     1m12.841s

Now I'm emerging -e world with -Os. When it is finished, I'll mail you the results.
