It seems 4.3.2-rX isn't filtering -j5 anymore (AT-FUCKING-LAST):
| Code: | Mon Dec 15 19:32:18 2008 >>> sys-devel/gcc-4.3.2
merge time: 55 minutes and 53 seconds.
Mon Jan 5 16:57:14 2009 >>> sys-devel/gcc-4.3.2-r2
merge time: 17 minutes and 2 seconds. |
This is in a non-overclocked Q6600. I haven't tried in my OCed desktop one.

The top one of mine is non-overclocked: | Code: | george@leviathon ~ $ genlop -t gcc

they are both with -j7, I think the bottom one is about 3.1Ghz, so it makes about 2 mins difference  |

cokey: try MAKEOPTS="-j" and tell me how it comes out on that box... should be a bit faster.

Why don't you just run yes for that?

My old 4.1.2 compile times are horrendous, because they still filtered -j at that time:
| Code: | Mon Feb 18 12:10:11 2008 >>> sys-devel/gcc-4.1.2
merge time: 32 minutes and 10 seconds. |
although obviously not as bad as 4.3.2 (4.3.2 actually builds the compiler *twice*; that's why it takes almost one hour with a single core).
