Now, several users have taken to the Firefox subreddit to complain about high CPU usage when using the feature, as well as express their disappointment in Mozilla for adding AI to the browser.

I don't think it even downloads the model if you never enable or use it.

I love that people get upset that their CPU is using its resources when they're using it.

[–] Psythik@lemmy.world 23 points 22 hours ago (2 children)

Reminds me of how some people get upset when their OS uses up all their RAM, no matter how much they have. It's like they want their PC to be sluggish and unresponsive. Unused RAM is wasted RAM.

Did a project several years where the customrr required that the server we delivered specifically for the project never use more than 50% CPU or RAM. No requirements about how fast it actually performs its intended function, just that it can only utilise half the available resources while doing it.

[–] AFKBRBChocolate@lemmy.ca 7 points 15 hours ago (1 children)

Probably a bleed-over from the embedded side. Spent a lot of years working embedded control systems for NASA and DoD - bare metal systems, often interrupt driven - and it was common to have 50% margin requirements. They know those systems will grow over time, and they often have lifespans measured in decades.

[–] Buckshot@programming.dev 4 points 14 hours ago (1 children)

That would make sense, i hadn't put that together but they had a lot of embedded control systems. This was water treatment but entirely separate from the control systems but i can see them having that a standard requirement

[–] AFKBRBChocolate@lemmy.ca 2 points 13 hours ago (1 children)

So was it a government (state or federal) water treatment plant? If so, I can tell you how it happened. The government contracting agencies have boilerplate text they're supposed to add to contracts to make sure salient requirements get flowed. They're supposed to delete or tailor anything that doesn't make sense, but the contracts people aren't usually very technical. We had requirements flowed to us about password management and account monitoring, but no one logs into a rocket engine or a torpedo. When we'd point it out, they'd say "oops, we should have deleted that."

[–] Buckshot@programming.dev 2 points 13 hours ago

Not in the US, our water infrastructure was sold off in 90s but that makes sense. Was probably something similar They held us to it though so they overpaid for hardware beyond their needs and we forced the software to run slower

[–] addie@feddit.uk 3 points 20 hours ago

Yeah, we have that with our customers sometimes. To me, an app should either be running full whack - maxing out bandwidth on CPU, disk, memory or network - or completely idle. Chuntering along at 2% is a bug. For the ones that put 'monitoring tools' that raise errors when we reach 100% on something, we set a Linux CGroup to throttle the offending resource. Takes longer, obviously, but not worth arguing with their network deployment teams 🤷 .

That RAM is mint condition collectors edition RAM. We're just storing it there temporarily.

Don't you dare fucking touch it.

[–] Blackmist@feddit.uk 1 points 20 hours ago

My software does that anyway because I can't be arsed with multithreading or a 64 bit version

[–] Dreaming_Novaling@lemmy.zip 1 points 17 hours ago

Actually, I'm kinda sad that my laptop doesn't get close to maxing my RAM cause I specifically bought another stick to make it 16GB. This was back when I was using Windows but now I'm bloat-free on Fedoora. I need to get into gaming on my laptop instead now lol.

[–] callouscomic@lemmy.zip 1 points 18 hours ago

Why don't they download more CPU? Are they stupid?

[–] mannycalavera@feddit.uk 0 points 19 hours ago

I want my cou to be idle all the time! Damn it why did I spend so much on a CPU only for it to "do work"? FFS.

"I've noticed that my CPU, GPU, and power usage goes up when I run games. Valve needs to fix this ASAP! Steam is literally unusable!"

[–] BD89@lemmy.sdf.org 7 points 21 hours ago (1 children)

Isn't this enabled by default? And don't you have to manually edit the config settings in the browser to disable it?

[–] RaivoKulli@sopuli.xyz 3 points 21 hours ago (1 children)

It wasn't for me

browser.tabs.groups.smart.enabled = false

[–] Kissaki@feddit.org 8 points 20 hours ago (1 children)

I haven't used it and it is enabled in about:config for me.

[–] RaivoKulli@sopuli.xyz 1 points 19 hours ago (2 children)

Have you used the tab groups?

[–] Kissaki@feddit.org 2 points 19 hours ago* (last edited 19 hours ago)

No, I haven't used tab groups. At least not beyond an initial peek when they were introduced. They're no replacement or useful addition to my vertical hierarchical tabs (Tree Style Tab extension).

[–] BD89@lemmy.sdf.org 2 points 14 hours ago

You mean that annoying shit they do where I'm trying to move one tab and it puts it in a colored square with some bullshit?

Yeah there was NO WAY TO AVOID THAT. It straight up did that shit on its own. Like literally it almost magnetically attracted itself to the other tab to pull this shit. It effectively activates it for you this way whether you want it or not.

Man even Firefox is starting to shit the bed with their decision making.
