 Posted: Wed May 30, 2018 7:36 pm Post subject: [SOLVED] Minimal Install CD Slow compiling |
 |
|
Tried it a few days ago, and it took ages to compile GCC with my Intel I3 Coffe Lake, compared to when I have used the Systemrescue CD. I noticed first something was wrong when I extracted the stage3 and portage snapshot, as it was very slow too. I had to break the installation, and start over again with Systemrescue CD.

The compilation time should not depend on the type of installation medium

Something wrong with the kernel config maybe? |

ayeyes,
What CPU governor is set?
The powersave CPU governor fixes the clock at the lowest permitted frequency. That's good for laptops prone to overheating but very bad for compile times.
| Code: | # cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
ondemand |
| Code: | | cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors |
will show what's built in.

Thank you NeddySeagoon!
I got 'no such file or directory'. There is | Code: | | /sys/devices/system/cpu/cpufreq |
but it's empty. In | Code: | | /sys/devices/system/cpu/cpu0 |
there is no 'cpufreq'.
Did a dmesg, and the output scrolled slow. |

Also with intel p-state?

fedeliallalinea,
I don't know about Intel.

Thanks to iamben @ #gentoo it's solved. Booting with gentoo-nofb did the trick. 
How come?

I was told that installing with the mininal install cd and "gentoo-nofb" it could do serious harm to cpu by overheating, as it didn't have a "scaler" for my cpu (Intel i3 8350k).
Is that right?
With high framebuffer console with SystemrescueCD it's slow too, even though it has the powersave governor. |

Thank you Jaglover. I didn't have a load balancer when I tried it without nofb. Had 'MAKEOPTS="-j4'.
Will try with
| Code: | MAKEOPTS="-j4 -l4"
EMERGE_DEFAULT_OPTS="--jobs=4 --load-average=4" |
which makes it quiet too.
+ That did the trick. Thanks once again. |

| I wonder why nobody's stepped up to fix the fbcon drivers. It's always been slow but it's getting worse, probably costing years of lost productivity... |

Ant P. ... sounds a lot like x11/mesa :) ... every update for the past two or more years has been worse than the last, using a terminal is like watching syrup in slow motion. I've come to the conclusion that older hardware, that at one point run linux/gentoo perfectly fine, nolonger does, because I need to be spending money (I don't have) to keep up with "developments".
best ... khay |
