Chromium build time 36 hours??

Message

hariskar · Post by **hariskar** » Fri Jan 27, 2023 2:39 pm

I just installed gentoo, compiled Chromium in about 36 hours...
Is my PC extremely weak and outdated? Do I have wrong settings?
RAM is 16GB.

Do I have to update cpu, mb, ram?
Thank you!

In my i7-4930K 32GB and makeopts -j12 latest chromium I compiled (100.0.4896.75) took 5:39:33.
After that I installed www-client/chromium-bin the precompiled version.

So, it is normal for my PC to make that long..
I don't want to install bin, 5-6 hours would be OK for me, so I guess I have to update my hardware..

Note that qlop is a simple log parser. If there is any sleep/hibernate involved, it will skew the output.
The log will only contain when it starts and stops and does not take into account other factors.

I try with ccache to see if there is a significant improvement..

There won't be. Instead, it'll likely bring unexpected compilation errors. I'm surprised it takes so long. It's comparable to the Q6600 with 8GB of RAM I used to run Gentoo on an year ago. Maybe try to swap your CPU with one that supports HT.

I don't know why you're reluctant to use the bin version. Despite I have a Ryzen 7 5800H I moved to binary packages for libreoffice, rust, firefox, chroimum (ungoogled chromium from pf4public overlay). Back when I used the Q6600, I used to enable LTO on ungoogled-chromium which brought some improvement in the performance, but I'm not sure it's worth given the long compilation times. It took ~40 hours for me back then.

Best Regards,
Georgi

The motherboard is old (socket 1150), so I guess I have to swap also motherboard and maybe RAM..

of course, be aware!

compiling time depends on many things - CPU - disk speed - kernel?!, etc.

i have a fast NVME and ccache is on separate fast NVME - no SWAP.

without ccache, chromium take more than 8 hours, while browsing with FF and watching stream with chromium.

Yeah, ccache will not do much when compiling a new version, but it should definitely help with rebuilds.

Well, I generally only build Chromium in Qt WebEngine, which luckily still has the 'jumbo-build' option being maintained, so I don't really have experience on plain Chromium itself.

Out of curiosity, with a Ryzen 7 1700 using 14 of the available 16 threads (the older builds are with a 6-core Phenom by the by):

       merge time: 6 hours, 44 minutes and 37 seconds.

Here's qtwebengine-6.4.2[jumbo-build] (which didn't get a 100% full use of the 16 threads either, but I did not limit it to 14):

Thank you, I suppose compilation time of ungoogled-chromium should be about the same?

Yes, but you could enable LTO, which in my case gave some performance benefits. There is ungoogled-chromium-bin too.

After I changed to (entry level) Ryzen 5 5600G compilation time of Chromium dropped to 4 hours (it was 36-40 with previous hardware!
4 hours is a totally acceptable time!
Thanks again for replies!

That is a modern cpu, only 2 years old.
I don't use chromium, but I think that 4 hours is a very long time for that cpu.
On an i5 7400, librewolf with lto and pgo takes 2.5 hours to compile.
Those flags double the compile time.

If my 6 year old cpu with 4 cores and 4 threads can do this, surely yours can do better.

Firefox compiled in about 4 hours with my old cpu. Chromium is much more demanding...

RAM is OK for 8 threads, but your CPU only has 4 of them. The build time is comparable to my old Q6600 with 4 cores/4threads and 8Gb RAM. If your MB supports Hiperthreading or 8 core CPU without HT, that could be an easy upgrade. However I don't remember Intel desktop CPU's from that generation supporting HT.

Chromium used to compile for shorter times when they used the jumboo build which merged header files, but now they removed it and we're stuck with loading and compiling countless header files over and over again. Pre-compiled headers is not supported, neither it works, at least for GCC afar.

That's a lucky run. Ccache has proven to be more of a problem rather than a solution. It doesn't benefit compile times even between minor versions as changes have too wide of an impact.

There won't be and in your case a single failure will wipe out all the benefit. Ccache is known to cause build failures. Better look for an 8thread or 8core CPU. There's also chromium bin version as well as ungoogled chromium bin, if you don't like the original. And I think there's a binary package of chromium produced by the experimental Gentoo binhost.

It seems like when compiling Chromium it really matters how many CPU threads system has.
Two years ago I did a lot of compiling tests on the same motherboard, with 3 different Xeon E5-2XXX flavors:

In dual-CPU configuration, the same number of memory channels and same type of memory sticks were used for both CPU.

I made a few conclusions (though I am not an expert in this field, my knowledge comes from tests):
a) You may have less powerful single-threaded CPU (E5-2697) which will outperform more powerful one (E5-2687W), because E5-2697 has more threads;
b) It really matters how much memory each thread has. If it system has 2GiB per CPU thread or less, chances are that due to swapping system will not compile Chromium.
c) It is important to balance memory sticks over memory channels. This is less important than having more CPU threads/cores, still, there is a room for optimization here.
d) Having a lot of CPU cores and memory is important to compile Chromium. Chromium build needs about 4-5 GiB per core/thread to be happy.
e) Memory speed plays a role a bit, but not as much as changing CPU.

P.S. If you find a typo/error, please do not judge me harshly, I copy-pasted all this info from different places in my benchmark log.

That's a lucky run. Ccache has proven to be more of a problem rather than a solution. It doesn't benefit compile times even between minor versions as changes have too wide of an impact.

yes, you're right

sometimes it helps, sometimes not - here are some examples including todays merge:

This must include a few terminated builds.
BTW with a fast enough CPU, ccache is in fact a hurdle. I tried with Ryzen 7 5800H and 32Gb RAM and it didn't make a difference for one and the same version, compiled two times. It actually made my CPU hotter.

yes, you're right - without ccache, it takes more than 8 hours to build, on my system.

32G RAM, of which 24G is devoted to /tmp (tmpfs) and portage configured to use /tmp, not /var/portage/tmp.
I figure RAM disk would be faster than SSD...
