Greetings. I recently purchased a Lenovo v15 g4 laptop, intel core i7 processor. It's not "officially" support, but I've installed FreeBSD 15 and I've managed to get it working pretty well. There are still a couple of issues with suspend/resume and bluetooth. Anyone available for a couple of questions?

numberoneson: good job +1

looks like a nice laptop

Thanks. I'm pretty happy so far. It would be nice to get bluetooth working, though, and I'm afraid that's outside my area of expertise. usbconfig shows it's there and apparently alive, but I can't configure it.

15 really is a gigantic step backward on my machines performance wise. I think I am going to roll back at least a couple of them to 14, ugh.

amigan: Is the performance lose across the board or I/O related?

It seems to be all IO related.

I installed 15 on this lenovo laptop since I needed up to date iwlwifi, but I've noticed that IO seems a lot poorer than I'd expected. I was thinking/hoping I could buy a higher end ssd but now I don't know if it's worth it.

Network, disk, doesn't matter. And I'm seeing some very weird behaviors, for example I always had alias precmd 'history -S; history -M' to merge the histfile across multiple shells. Under 15, it takes comparatively forever to complete this precmd and return a new prompt. I ktraced the shell and it's stuck in a giant block of thousands of sigprocmask(2) and setitimer(2)

On another machine, garage (an S3-compatible object store daemon) saturating the disks leads to utter 5 second hangups of ssh just echoing characters

Seeing behaviors on amd64 boxes, aarch64, zfs and UFS

Interesting. I'll try the same thing & see what I get. I have a 5+ year old dell tower running 14.3 and it's prob twice the speed of this new laptop.

Yeah. And my firewall apparently can no longer do line speed with iperf in one direction. Tops out at 570Mb/s, even with pf disabled.

No bencharks, though. I'm just comparing how it feels/acts while eg compiling in the background.

Yes, same here. I'm just going by every day use. Also, poudriere runs definitely take longer.

Hmm. My firewall is opnsense on a small supermicro. They're still using 14.

No problems there.

I'm a moron and upgraded everyone at once. I've never regretted it before.

Firewall is just vanilla FreeBSD

:) Same... I've just spent enough time getting 15 usable on this laptop that I haven't had time to upgrade my others yet.

FWIW I've been very happy with opnsense.

Yeah, I would hold off. Normally I am totally fine with being a guinea pig and report bugs but this is kind of ridiculous

You know what they say about .0 releases.

But I'm going to try to collect some useful data, anyhow.

Lol, yeah. But none of the .0s I've gone through in the past were bad. It was always a step forward.

I

wonder if pkgbase will make downgrading less painful

Some of these machines are UFS and while I do have full backups of 14, it will be a pain

I'd be interested to hear how it goes. The spirit hasn't yet moved me to switch to pkgbase.

I'm thinking, downgrade base, and downgrade packages before rebooting so I don't run into any ABI incompatibilities

Yeah. pkgbase is definitely a step forward. I build -STABLE for my whole network normally, and mounting /usr/src /usr/obj over NFS was always janky af

i didn't find nfs:/usr/obj janky at al

l

It worked, sure. But it was not as clean as pkgbase

I've been doing NFS /usr/obj for 20 years, this is nicer

Sounds good. I'm tempted to buy a new drive (i'm afraid prices are going to shoot through the roof thanks to ai...) and try it that way. I have good backups.

I've also been using NFS /usr/obj for many years & it works, which is a big part of why I haven't experimented with pkgbase yet. Thanks for the push..

Yeah, the best time to start building and hoarding components was 6 months ago. The next best time is right now. I just built a box a few weeks ago, my first in a decade. Hope it lasts me another decade considering how much I spent on dram.

OK, my plan is now to buy a new 2tb drive, add it to my tower, & install 15 on it. Then I can compare buildworlds/compiling libreoffice.

Or compiling rust. Both are pretty time-consuming.

Yup, rust, llvm19 (for postgres), and mongodb are the heavyweights in my poudriere runs. If you try to MAKE_JOBS llvm it will just start ooming. Working set sizes over 2GB per process during LTO

I was really excited to move my big hypervisor (the new box) from linux to FreeBSD but I don't think it's in the cards for a bit with these regressions.

I'm actually pretty new to irc; just getting started. But I plan to stick around & I plan to share my results after a 14.3-15 side-by-side comparison.

amigan: are you on 15/stable or -release?

i just started moving 3 of my systems to 15/stable from source but i'll keep an eye out for any noticible perf regressions
