The only way i know to migrate to 64bit is a reinstallation. But the |
| 24 |
config files are the same of cause, so it should not be so hard as the |
| 25 |
first install if you save your /etc and /home. |
| 26 |
|
| 27 |
The CPU vendors tell, that 64bit code is faster on their 64bit capable |
| 28 |
CPUs. Personally i newer thought, "oh yes i feel it, this is 64bit". If |
| 29 |
there is a speed gain, it is marginal or only in special cases. |
| 30 |
|
| 31 |
So if you only want to switch to 64bit because of the memory, you could |
| 32 |
also use PAE till you want to reinstall anyway. |
| 33 |
Nevertheless 64bit on a 64bit capable CPU seems like the way to go :-). |
