I've got an underpowered netbook that needs all the help it can get. |
| 8 |
I build in the VM with... |
| 9 |
|
| 10 |
-O2 -march=bonnell -mfpmath=sse -pipe -fomit-frame-pointer -fno-unwind-tables -fno-asynchronous-unwind-tables |

Even older desktops benefit. One case in point is my former Dell |
| 13 |
D530 Core2 Duo. When Gentoo had been installed, it could not keep up |
| 14 |
with the slowest stream of NHL Gamecenter Live. Everything was generic |
| 15 |
x86 with SSE2 thrown in, from the stage3. After re-emerging system and |
| 16 |
world optimized for the machine's cpu, it could keep up with not only |
| 17 |
the lowest quality stream, but a medium-quality stream. So yes, it |
| 18 |
helps. |

From http://gentoo-en.vfose.ru/wiki/Safe_Cflags#-march.3Dnative to |
| 21 |
find out exactly what your cpu is, run the following command on the |
| 22 |
*TARGET* machine... |
| 23 |
|
| 24 |
gcc -march=native -E -v - </dev/null 2>&1 | grep cc1 |
| 25 |
|
| 26 |
Ignore the flag output, which may be over-optimistic. Just look at |
| 27 |
what it says for "-march=". |
