Nothing much. Use like normal x86 besides: |
2 |
- Kernel set to Your CPU in Processor Setttings (generic x86_64 is good for |
3 |
all configurations). |
4 |
- Accept keyword for "Beta"-like packages is ~amd64 not ~x86 |
5 |
- You don't have to set MMX flag, but set SSE, SSE2 and if Your CPU have it |
6 |
- SSE3 this will optimize floating point operations. |
7 |
- Enable SMP (symmetric Multiprocessing) where available - by flags. |
8 |
- If it's multicore (I have Intel on my LAP so don't know about Your CPU) |
9 |
set MAKEOPTS to cores count+1. |
10 |
- If it's multicore try to enable threads flag - this boosts performance |
11 |
even on single core cpus, but on multicore will make much difference. |
12 |
- Chceck by eselect what profile of portage you have set as default. If is |
13 |
not try setting some with Amd64 on path. |
14 |
- When GCC upgrade check if "multilib" is set - this will enable You to link |
15 |
with 32-bit libs and 64-bit (as standard). |
16 |
- In kernel set ciphers and algorithms (like MD5, SHA etc) to amd64 version. |

I think that's it. Everything elese should be fine. |
