 Posted: Sat Dec 09, 2023 5:33 am Post subject: post your build times and specs |
 |
|
Hello,
***Disclaimer: this post is just to chat about packages' build time and collect information that might help others searching for it.***
I know that the wiki provide some hints about build times and RAM needed for them, but that info is not applicable to everyone and might be outdated. So, I starter searching around for anyone posting or blogging about any packages' build time and the specs used, but there is none. I was hesitant for awhile to build big packages, but today I decided to test my machine by building thunderbird and I expected it to take about 3 hrs. However, it took a lot less than that!
So, I'm hoping that you guys participate by posting your build times and specs for anyone seeking a general idea about their hardware and its capabilities.
Here are the build times of thunderbird & friends, and specs of my machine:
| Code: | root@~ # genlop -t thunderbird
* mail-client/thunderbird
Fri Dec 8 23:06:02 2023 >>> mail-client/thunderbird-115.5.0
merge time: 32 minutes and 31 seconds.
root@~ # genlop -t nodejs
* net-libs/nodejs
Fri Dec 8 22:28:32 2023 >>> net-libs/nodejs-20.6.1
merge time: 27 minutes and 33 seconds.
root@~ # genlop -t openh264
* media-libs/openh264
Fri Dec 8 22:00:39 2023 >>> media-libs/openh264-2.3.1-r3
merge time: 15 seconds.
root@~ # genlop -t botan
* dev-libs/botan
Fri Dec 8 22:29:45 2023 >>> dev-libs/botan-2.19.3-r2
merge time: 1 minute and 6 seconds.

All the posts so far seem to have consistent merge times, but that is excessive! I bet you if you merge chromium multiple times a week, that ARM CPU is going to cease functioning. Those little computers are not meant for compiling software, at least not large projects, but thank you for experimenting. |

| It's always interesting to see compile times of big packages on different machines, but I'd suggest adding at least LTO and PGO useflags, too. |

myga,
It never goes over a CPU temp of 60C.
gorg86,
PGO will at least double the build time as the package will be built twice.
LTO will drive a lot more swapping as its a memory hog.
I do use LTO on my Pi4 build system (with 128G RAM) but it won't run code built for the Pi5 which makes building Pi5 optimised code a bit tedious.
All the Pi5 code on my binhost is actually built on the Pi5 just now.
distcc would help a bit, maybe, but that's a double edged sword.
The rest, is Pi4 optimised with LTO but not PGO.
| Code: | # genlop -t chromium
* www-client/chromium
Wed Nov 15 15:06:07 2023 >>> www-client/chromium-119.0.6045.123
merge time: 17 hours, 43 minutes and 1 second. |
That's with 32 3.3GHz cores, 128G RAM and LTO.
On an 8G Pi4 ...
| Code: | #genlop -t chromium
* www-client/chromium
Thu Oct 26 23:08:54 2023 >>> www-client/chromium-119.0.6045.21
merge time: 3 days, 10 hours, 26 minutes and 57 seconds. |
I was looking for a build error but it built. No LTO or PGO there either.

I used Gentoo for ~5 years, and it was the first OS I installed on my last computer: https://www.cpubenchmark.net/compare/4814vs1920/AMD-Ryzen-7-5700X-vs-AMD-A10-5750M-APU
That machine was my daily driver for ten years, up until last week. I had been using OpenBSD for awhile, but switched back to Linux for the hardware support, and so Gentoo is the first install on this machine as well. The specs:
Ryzen 7 5700X
32x2 GB @ 3600
Radeon RX 6600 (8 GB VRAM)
As for build times, my old machine took several hours to build Rust, Clang, GHC, etc. As the benchmark numbers suggest, builds are ~14 times faster on this machine.
I think the increases in build time are because I added the LTO and vectorization flags a few days ago.
| Code: | COMMON_FLAGS="-O2 -pipe -march=native -flto=auto -ftree-vectorize -fvect-cost-model=very-cheap"

This is USE="-pgo -lto +fortran". My build times are all suspect as I use distcc and --jobs > 1 ... With careful planning, even my rust qlop times are not completely indicative of the local machine's build speed.

My God! That's a long time to wait. I remember when I used to compile Firefox on FreeBSD, I leave it overnight too.
How were you able to compile GCC anyway? This is a quote from the Wiki:
| Quote: | | More than 4 GBs (will fail with <= 4 GBs), and even more if Java and Objective C are also included. |

That's not bad at all. But if you attempt to emerge Chromium, you will be waiting a while and from my experience with AMD, it'll generate more heat than a motorcycle on a hot summer day.
BTW, I got two old computers, one is Dell Vostro 220s (32bit) with Pentium 2200 CPU and the other is Compaq (64bit) with an Athlon II CPU. Yall are welcome to take them for your labs. |

My Pentium-M 1.6GHz (1.5GiB RAM) and Atom N270 (2GiB RAM) haven't quite reached their Gentoo refresh cycle yet... For kicks I tend to update them (both 32 bit) to latest about once a year. The N270 with distcc help still takes 5 days 24h/day compiling, and the Pentium-M is not far behind - both building firefox and its dependencies...
Luckily I really don't need these machines up so they can just build in the background.
Incidentally I've had LTO going for rust and I had the rust RSS go to almost 7GiB.
My A6-3420 (quad core):
2023-11-04T02:48:08 >>> dev-lang/rust-1.71.1: 3:14:27
It only has 7.5GiB RAM because 512MB is swallowed up by the on-die graphics (wish I could reduce it, I don't do graphics that much on this machine. Can't wait until I could do open CL on it so that 512MB could actually be useful...) Again this is with distcc help... My dual core i5-3317 with 16GiB RAM actually was significantly faster (about 2 hours) probably because of the lack of need to swap, I figure.

@krumpf thank you, the comparison of the two CPU's with differenct Cores was very interesting, even if a different gcc and kernelversion also impact on build times.
Here my little workstation:
| Quote: | Kernel: 6.6.7
CPU: Intel Celeron N5105 (4x 2.9 GHz)
RAM: 16GB (50% as tmpfs) |
| Code: | rene@gentoo ~ $ genlop -t firefox thunderbird nodejs
* www-client/firefox
Sat Dec 16 15:34:14 2023 >>> www-client/firefox-115.5.0
merge time: 1 hour, 37 minutes and 17 seconds.
* mail-client/thunderbird
Sat Dec 16 10:52:55 2023 >>> mail-client/thunderbird-115.5.0
merge time: 1 hour, 44 minutes and 4 seconds.
* net-libs/nodejs
Thu Dec 14 06:51:30 2023 >>> net-libs/nodejs-20.6.1
merge time: 1 hour, 29 minutes and 20 seconds. |
I was interested in testing the impact of different kernel versions on a larger package. The result surprised me; I expected a larger difference over time.
##updating #5 and #6
#1 = gentoo-sources-6.6.6
#2 = gentoo-kernel-bin-6.1.67
#3 = gentoo-kernel-bin-6.6.7
#4 = gentoo-sources-6.6.7
#5 = gentoo-kernel-6.1.67
#6 = gentoo-kernel-6.6.8

The one that took 4 hours is funny. No idea why it takes a bit more than 30 minutes one time and almost an hour the other time. I would think it would always be similar on the same pc when you don't change things like cpu or memory.

Today I realized that www-client/thunderbird was built with clang USE FLAG and caused a build error. I removed it and emerged again and it looks it took longer to build this time.
| Code: | # genlop -t thunderbird

I would hope these are not as corrupted by distcc but they may well still be due to --jobs ...

A funny one (A106800K @ 4.1Ghz Piledriver)
| Code: | Tue Jun 27 04:00:07 2023 >>> sys-devel/gcc-12.3.1_p20230526
merge time: 10 hours, 7 minutes and 25 seconds.
Thu Oct 19 01:02:37 2023 >>> sys-devel/gcc-12.3.1_p20230825
merge time: 4 hours, 33 minutes and 27 seconds. |
I was very surprised (and pleased) to see the speed improvement. What happened ? Same use flags (ada, lto, pgo, objc..) and both compiled while nothing else was running. |

the flags lto and pgo quadruple build time and I don't see a reason for me to use them. Your build time was reduced significantly due to gcc not needing to rebuild most or all of its code and only the code that was committed is what was built. |

Firefox examples probably aren't great since I normally use www-client/librewolf-bin for my browser which is why those are crazy old versions, but those were compiled with lto and pgo fwiw. |

I suggest using a command like:
| Code: | | qlist -Iv | xargs sudo qlop -Mma | sort -k 2 -nr | head -n 10 |
In order to obtain the 10 longest-to-compile packages on any given system.
For me, that is:
| Code: | dev-qt/qtwebengine: 16327 average for 1 merge
sys-devel/gcc: 12383 average for 1 merge
app-office/libreoffice: 7795 average for 1 merge
sys-devel/llvm: 6484 average for 6 merges
www-client/firefox: 5410 average for 1 merge
dev-lang/rust: 5098 average for 1 merge
sys-devel/clang: 4253 average for 3 merges
app-doc/doxygen: 4154 average for 1 merge
net-libs/nodejs: 4027 average for 1 merge
dev-util/mingw64-toolchain: 3676 average for 1 merge
|
Some averages here are skewed due to the occasional binary merge (downgrading llvm or gcc, primarily).
| Code: | $ sudo genlop -t dev-qt/qtwebengine sys-devel/gcc app-office/libreoffice sys-devel/llvm www-client/firefox

Nice one. You don't need sudo for qlop though.
Edit: Nevermind, you actually do. My current user was still in the Portage group when I wrote this

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