do you have running many other tasks when you do your emerge world ?

Sorry for the delay .. I really don't have any heavy processes running. I have plenty of ram (128g). I have not however built my own kernel, I use genkernel. In the early 2000's I was manually building for basic processing speed, not that important in today's world of computing. I suppose I should give it a try. My system has been so stable for the last few years since returning to Linux ... Gentoo!. I have forgotten more than I know. (The kernel could be the problem)

Maybe. Maybe not. Do you use parallel compiling (EMERGE_DEFAULT_OPTS) or do you have a lower MAKEOPTS= (as said before I used =24)

If you want I could take a look to your kernel config (just use wgetpaste for this).

(Maybe you know this all already, but if not ...

I have MAKE OPTS= -j24 and I am not using EMERGE_DEFAULT_OPTS. I re-emerged gcc to make sure my upgrade from 12900k was represented. Firefox and Thunderbird are 40% to 50% faster with the 13900k.

gcc is only about 20% faster. Temps can hit low 90's at times. Perhaps throttling.

When things slow down I need to better optimize my kernel.

Thanks for your involvement!

Did an install on my HP Compaq 6710b. I went with Plasma and Wayland.
The official Gentoo binhost definitely helped, although many packages still had to be compiled.
I had to stick with -j1 for sys-devel/gcc, else the compilation would fail.

Going through its yearly update: Pentium-M 1.6GHz (1C1T Dothan, 32-bit only), 1.5GiB RAM, mechanical HDD, distcc (had to cut real low as it kept OOM'ing, so -lto -pgo)

It's still working on update... but a bit faster than my Atom N270.

Crappy rust and llvm recently seemed to have started to do something that really kills computers with low memory, had to reduce -j down really low to finish where it had been fine before. -j had been nice because rust's llvm and llvm itself of course can be distcc'ed. But now not so much if the higher -j number runs out of memory during one lousy step...

My Laptop with -j4 und -j3 and 8GB-Ram run out-of-memory while compiling llvm-17.0.6. I do not use swap, so i configured zram, this worked good

My 1.5GiB computer (laptop) wishes it had 8GiB!
Using lots of swap didn't help... llvm-tblgen is awful.

both systems are:
Ryzen 3700x
64 GB
/var/tmp/portage mounted on tmpfs with swap on SSD if it's necessary
driver: amd-pstate-epp
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: Cannot determine or is not supported.
hardware limits: 550 MHz - 4.43 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 550 MHz and 4.43 GHz.
The governor "powersave" may decide which speed to use
within this range.

EMERGE_DEFAULT_OPTS="--verbose --jobs=16 --load-average=16.0 --with-bdeps=y --autounmask-keep-masks"
MAKEOPTS="-j16 -l16"
CCACHE_SIZE="100G" (on SSD)

with identical (or close to it) USE flags and packages installed, with alpha also being a lightly used server (web, email, ftp, backups).
Both running Mate/Xorg, with two browsers and thunderbird open

Updates happen daily and as my make settings show, are compiled in parallel with other packages that could affect build time, which ccache can also affect. Interestingly, with ccache, some extremely long builds, like ungoogled-chromium, can take 4 hours on 1 machine and 1 hour on the other machine, depending on what all happened to get saved and had a cache hit. ungoogled-chromium is a nightmare that I usually build by itself. Unfortunately, some websites don't want to work properly with anything but chrome, so I have to keep it around. The enshittification of the web, brought to you by google. Who needs standards when we can relive the Netscape/IE web of the 90s?
