| As subject, with -march=native and 4gb ram, approx how long should emerging gcc-4.4 take on an i5 650? |

GCC takes forever on any processor.
I would guess on an I5 little over 2 hours. |

That's my build and i really hope that the i5 chip would perform better than 2 hours 
| Code: | genlop -i =sys-devel/gcc-4.4.4
* sys-devel/gcc
Total builds: 1
Global build time: 33 minutes and 14 seconds.
Info about currently installed ebuild:
* sys-devel/gcc-4.4.4
Install date: Thu Jun 10 20:40:27 2010
USE=""
CFLAGS="-march=athlon64-sse3 -O2 -pipe" |

| What, one of my friend use a Core I5 and it took 72 minutes to emerge -e system, so basically, it's suppose to be pretty fast. |

Seriously?
According to genlop, 4.4 emerges in just under 10 minutes on my phenom...

On my system:
# time emerge -1 sys-devel/gcc
real 11m6.854s
user 49m34.886s
sys 6m21.723s
Although I have to say this was with on-demand frequency scaling, and it kept going down to 1.6 ghz briefly for some reason. Max is 2.67 ghz.
I don't have an i5, but seeing results from an i7 920 might give you an idea.
PS: I forgot to mention that I have /var/tmp/portage mounted as tmpfs.
PPS: I tried it again locking it to 2.67 ghz, got this:
real 10m46.801s
user 49m36.565s
sys 6m19.212s |

| Tmpfs can save you less then 10% in some situations. |

| Would ccache have affected any of those times? Just tried a very quick test install, emerge -e system took about 3 hours with gcc taking well over an hour. What could be wrong? |

Really? I'm on a Phenom II X4 810 and I build it in under 17 minutes.
| Code: | Thu Jun 10 17:22:42 2010 >>> sys-devel/gcc-4.4.4
merge time: 16 minutes and 36 seconds. |
It won't be 2 hours for an i5, it should be under 30 minutes.

Hi,
| Code: |
/dev/sda:
Timing cached reads: 13944 MB in 2.00 seconds = 6980.58 MB/sec
Timing buffered disk reads: 330 MB in 3.00 seconds = 109.85 MB/sec

That's mine on my main box.
Right now, I have no idea where your problem come from. |

| Is this a laptop ? If so, are you sure that your current CPUFREQ is at maximum ? |

It usually finishes within an hour on my systems. Are you setting MAKEOPTS="-j5"? |

Takes me ~30 min on a dual core amd64 w/4G ram

Ok, now we gonna try this :
Add this inside your /etc/make.conf :
| Code: |
EMERGE_DEFAULT_OPTS="--jobs=5 --load-average=5.0 --with-bdeps y"
|
Now recompile gcc. |

--jobs=5 will make portage compile up to 5 packages at a time. GCC, being a single package, will not benefit from that. |

Can you post this :
| Code: |
# cat /proc/cpuinfo
|
Maybe your kernel doesn't see your 4 logicials CPU. |

I hope you are not referring to me, as I am not the one with the slow GCC compile times, but just in case:
