Caches have also grown, however, so while the absolute efficiency has gone down, the proportion of the cache that's inefficiently used has not.

Intel's 10th Generation Core processors are still current (despite the 11th and 12th generation existing), and have typically 8 MiB or 12 MiB of LLC (plus higher levels that are affected more by working set size than by total size); in 2007, the Core 2 Duo was the latest hotness, with 2 MiB of LLC (plus higher levels).

All the resources have grown significantly since 2007, and thus the "ideal" tradeoff point between needing infinite human time to get minimum resource usage, and needing infinite resources to get minimum human time has moved.

If things could be solved by brute force on computers, we would not need smart data structures, compression, optimised algorithms etc.

Installing another copy of, for example, mesa, on a system that already has one is simply sub-optimal. The only reason this is supposedly required in an open source ecosystem is because people refuse to come together and co-operate. And that will always be to everyone's detriment.

I understand that flatpak developers are trying to solve a real problem, which is amazing fragmentation of the open source ecosystem. The current result, unfortunately, has pretty serious side effects.

But the underlying shift is that because resources have become more abundant, it's easier to consume extra resources than it is to solve the social problems within the ecosystem - requiring people to have at least 3 GiB RAM has gone from "rules out most people" in 2007 to "virtually everyone meets this requirement" in 2022.

So that moves the balance point for what sub-optimal technology decisions you can accept in order to allow you to avoid dealing with people who aren't constructively helping. It would be nice if everyone involved in open source was constructive, but unfortunately, there exist people in all walks of life who consider it more important to be "right" by their own definition than to be constructive.

Oh god.

One of the of most significant advantages of Linux always was how efficient it is and how well it runs with limited computing resources. Personally I'm mostly using it on a desktop with i5-4460, and it runs as well as it did in 2014.

In my country, a lot of low-powered *new* laptops are beind sold to this day. Things with CPUs like Celeron N4020, 4 GBs of RAM, and HDDs, and people are buying them en masse because what else are you going to buy with a salary of $200-300 a month after taxes (which is what a cook or a construction worker typically makes)?

Teachers, doctors, and bureaucrats of all sorts are not doing much better.

Windows is pretty much unusable on those kinds of machines (although people are doing that and it's painful to watch). I'm sure there will be some distributions that will not go down the flatpak road and will still care about performance, but if all the popular ones do that, I'm afraid I will have nothing to recommend anymore (you're not going to recommend some student's side project that may be announced EOL a couple of days from now to a newbie).

Well, gentoo won't be going down that route, but it has other problems on low-powered machines ...

Cheers,

The comparison is even more stark if we move down from the high end CPUs to the low end; back in 2007, if you were in the market that today buys a Celeron N4020 (4 MiB LLC) with 4 GiB RAM, you'd have been buying a Celeron 365 or equivalent, with 512 KiB (0.5 MiB) LLC, and 512 MiB or 1 GiB of RAM.

Indeed, the gap between "as cheap as possible" and "low end for rich customers" machines has been shrinking over the last 15 years; you've gone from having 1/4 the RAM and 1/4 the LLC in an "as cheap as possible" machine as compared to "low end" to 1/2 to 1/3 the LLC and 1/2 the RAM of a low end machine for a rich person. The remaining gap is in mass storage - where a "low end" machine will have an SSD nowadays, a "cheap as possible" machine will still have a HDD because of the size differential between a $30 HDD and a $30 SSD.

That said, that gap may change, too - HDDs are limited in terms of how cheap they can be because they are precision mechanical systems, where an SSD scales down in cost; it was already true 8 years ago that if 30 GiB is sufficient space, an SSD was a cheaper option than a HDD, and the space on really cheap SSDs is likely to grow over time.

Honestly windows isn't that bad on these sorts of machines if you disable windows defender (which is .... rather involved)
