Hi, |
26 |
|
27 |
I've a desktop system and I commonly use applications like firefox, |
28 |
thunderbird and so on, kde, gaim and a terminal is nearly always there. |
29 |
Sometimes I'm running vim or kate. |
30 |
|
31 |
If you're interested in some tests, not relevant for desktop systems, |
32 |
there are some I made: |
33 |
|
34 |
Time wasted to compress a 416 mb tar: |
35 |
bzip2 gzip |
36 |
-O3 2m40.882s 1m20.445s |
37 |
-Os 2m39.314s 1m21.157s |
38 |
|
39 |
decompress: |
40 |
bzip2 gzip |
41 |
-O3 0m52.575s 0m4.972s |
42 |
-Os 0m53.387s 0m4.828s |
43 |
|
44 |
Convert 203 Mbs MP3s to WAV using LAME: |
45 |
-O3 14m4.461s |
46 |
-Os 16m50.599s |
47 |
|
48 |
from wav to mp3: |
49 |
-O3 1m1.708s |
50 |
-Os 1m12.841s |
51 |
|
52 |
Now I'm emerging -e world with -Os. When it is finished, I'll mail you |
53 |
the results. |
