With a 2.13Ghz pentium-m, I am using: |
| 11 |
CFLAGS="-march=pentium-m -Os -fomit-frame-pointer -pipe" |
| 12 |
|
| 13 |
I recommend using either -Os or -O3 with the pentium-m. In my |
| 14 |
experience, -Os and -O3 provide slightly better overall performance than |
| 15 |
-O2, although I should mention a few things will probably run slower. |

As far as mmx, sse, and the like, I'd say enable those through USE flags |
| 17 |
for those packages that support them. |

Also, be sure you are using the latest version (3.4.4) of gcc by running |
| 20 |
"gcc-config -l". |
