Hi,
Try (add)
src.conf:
WITHOUT_CLEAN=YES
WITH_MALLOC_PRODUCTION=YES
WITHOUT_LLVM_ASSERTIONS=yes
This may only give a result in subsequent builds, not on the first build or
when a lot or something essential has changed.
Note (just in case...) the make jobs number you use is not used for the
world, only for ports. For the world/kernel build it's really the -j option.
Bye,
Alexander.

Hi David,
* What (if any) "max_jobs" (make's "-j" parameter) are you using? 16
* For a 16T system, I expect I would start with a value of around 28.
Shouldn't this number be equal to $(nproc --all)?
* Are you using make's "meta" mode? I do. Yes.
* Can you get more memory for that system? Yes, I can bump it to 32GB. This
is a Dell OptiPlex 7080 Micro, and not sure if it is worth upgrading the
other components.
If your laptop can complete the builds in such a small amount of time, then
there's either something wrong with my machine or the config files. Oh! The

I'm trying to figure out a way to decrease build time of -CURRENT
and/or -STABLE but it is not working out that well.
I've tried the following:
* Tuning /etc/make.conf and /etc/src-env.conf based on their manpages
(make.conf(5), make(1), src.conf(5)).
* Removed certain options from GENERIC, which reduced the kernel build
time significantly.
Hardware specs:
* I7-10700T 8C/16T @2.0GHz.
* 16GB RAM.
* 256GB NVMe.
Currently, 'make buildworld' has been running for 7hrs and counting.
Is there anything else I can do to speed up world build?
....
First, some questions -- whether or not you wish to share the answers, I
believe that answering the questions (if only for yourself) may be
helpful:
* What (if any) "max_jobs" (make's "-j" parameter) are you using? For a
16T system, I expect I would start with a value of around 28.
* Are you using make's "meta" mode? I do.
* Can you get more memory for that system?
Some context: I am in the (definitely peculiar; perhaps unfortunate) habit
of "tracking" FreeBSD head and latest stable branch on a small collection
of machines ... daily. One of those is the laptop that I use for normal
"desktop" stuff, as well as accessing all other machines on the planet that
I access. (Oh: I also update ports daily, too -- though I let my dedicated
"build machine" handle chromium.)
That laptop has 4C/8T & 32 GB RAM. This morning, it took:
* 17:46 for stable/14-n269310-bbd018d0aaaf -> stable/14-n269315-b21c677ed28a
(0:02 to update /usr/src; 17:44 to build; 0:00 to delete old libraries)
* 24:03 for main-n273250-9d585fc395c3 -> main-n273270-cadb71e4b013
(0:03 to update /usr/src; 23:59 to build; 0:01 to delete old libraries)
* Updating ports (other than www/chromium) took 1:52.
(Those times are "mm:ss" in case it wasn't obvious.)
The above is fairly classic "sample size of 1" -- it's not necessarily
representative. Folks who are "sufficiently interested" are welcome to
trawl through the logs at
https://www.catwhisker.org/~david/FreeBSD/history/ to get a rough idea of
how long it is before the "uname" output from a successful build is logged;
there is probably some correlation to build times.
I also recently acquired a replacement "build machine": 64C/128T; 256 GB
RAM; a fistful of SATA SSDs (build/boot on one; the rest is a poudriere
play area in a zraid). That's a wee bit faster than the laptop. :-)
Peace,
david
