I was testing new Ubuntu 24.10 and wow 
the iso is 6.8GB download already.
After installing almost all apps are on snaps even you use terminal with apt it still installs them as snaps.
The biggest one is it uses memory like windows on boot I am already at 9.6GB memory usage and when 2 hours working it is already 22GB memory usage
Not sure if all this is there new approach for core desktop where everything is installed as snaps even kernel, desktop,apps etc
Heh guess 4.7 GB DVDs were phased out for a while; that’s huge 
I used 24.10 for a bit in a VM and didn’t notice any kind of mem usage like that; not even sure what I can do to reach that usage unintentionally It was about 2GB idle (same as other GNOME distros and F41).
I like Ubuntu’s approach to Snap; them doing Firefox was kind-of brave at first but seems good nowadays. There was also something with Steam and the Snap package had a cool graphics driver switcher (default, or edge with oibaf or kisak; limited to Steam vs system-wide).
Ubuntu feels more desktop-esk to me nowadays and I like running the same OS on my server and PC so I stopped using it a while back, but it’s still what I recommend to new users and what I’d install confidently to someone else’s PC.
What processes are using it?
(And it’s a broken record in many Linux forums, but it is worth keeping in mind that free memory is technically wasted memory, so used memory isn’t inherently bad unless it’s a runaway process or something, or unless it can’t be freed when needed)
I know this there is no process to use so much memory even spend 3 days to see and more hours I use more memory it gets taken eventually I got 90% men usage and laggy as hell and still can’t see what using all the memory
I had an issue a few weeks ago with GNOME System Monitor on openSUSE itself where it’d eat RAM as it was left open (I left it for an hour and had like 15GB usage plus Swap used). I haven’t seen that on Fedora, but I’m not sure what the issue was exactly or if it’s applicable to Ubuntu.
Does the Processes tab with sorted memory usage say anything notable? Might want to show All Processes (hamburger/drop-down) too. One oddity might be if you’re using ZFS on a large drive, in which case I’m thinking that memory usage would be shown.
4TB NVME all reserved on Ubuntu, ZFS with hardware encryption with TPM.
Process tree shows nothing suspicious or even glues and memory ramps even system monitor not open I opened it when system was getting slow and laggy
Why is Firefox as snap “brave”?
It is just convenient because you just have to make one for all the various releases.
Something went wrong, Mozilla made their own repository for deb packages.
Besides the technicalities, the big issue I see about snaps is the same as any other way to distribute software without supervision, it is the same as the “setup.exe” you download from any web site and pretty much changes the sense of “distribution” since snaps don’t come from the same place as “system” and there aren’t maintainers between developers (or somebody acting as developers) and the final user.
There have been some events lately that pretty much made the point very clear.
Did you write to the Ubuntu forum for this? You seem to have problems with Ubuntu so that’s the place to be.
Who me what?
It’s a largely-used core desktop app. Doing anything to Firefox of all things in a noticeable manner was brave, and people let Canonical know all about the initial shortcomings of that. It wasn’t rolled back; the Firefox Snap was improved over-time, and is pretty good nowadays.
Yes, I meant you since you are the original author of this thread and you have problems with Ubuntu. Sorry, I didn’t replay to your post so your name wan’t added, but to be honest I thought my answer would be obvious.
Who said I have problems? It is on water cooler with tech talk. I am also reported multiple issues to Ubuntu and testing a lot.
The way Ubuntu is doing things is similar to windows using apt you still get snaps not all apps convert to snaps yet, but more are coming rqch week on that style so Deb packages wre going away and snaps only. Memory usage high as windows and iso images reaching soon to 8Gb it was as actually on 7.8GB since it contained Cor base 22 and Cor base 24 snaps too
ZFS has a unique caching mechanism that will allocate a lot of RAM (I think up to 50%). As has been stated, it is supposed to free the memory immediately if any other program requests it. ZFS’s cache limits are adjustable, but it might slow things down if it has to (re)fetch files from disk more often.
Yet don’t see any “brave” move. Ubuntu exists for testing Canonical products and services. When Canonical enforces snaps on Ubuntu users that doesn’t mean snaps are the best idea ever for distributing software, it means snaps are good for business, they are meant to be deployed in Canonical corporate/business products and services. Who ever expected that to “roll back”?
What happened instead is Mozilla offers a “deb” repository that makes distributing Firefox as “snap” pretty much useless with the excuse of “it is too much a burden”. Given that you have Mozilla distributing both the “snap” and the “deb”, what is the point from the “user” perspective?
Problem with “snaps” and “snap store” is not performance or resource usage, it is the obvious fact that the “store” requires supervision, any “snap” must be verified. The “store” is like an external repo but publishers are unknown.
Brave to me means doing the change to end-users even if it’s a noticeable performance hit or “not ready”. Canonical did Firefox as Snap out-the-box default.
Had no idea Mozilla was offering a repo. If I was still using Ubuntu, I’d be using the Snap.
On an unrelated note, since they care about their browser’s presentation so much to be against Ubuntu Snap’ing it, they need to quit playing games and deliver their free privacy-respecting browser on Android in another place other than Play Store or having people trawl some outdated FTP HTTP interface
I 100% feel that with Flatpaks and yet people like those on Fedora
In Ubuntu’s case with default-providing Firefox as a Snap, there isn’t any additional verification needed with that. If you trust Ubuntu enough to be using it, you probably trust their default repos and packages. Afaik even with Firefox as Snap out-the-box, there’s no requirement to use anything else on the OS as a Snap.
There are more than Mozilla as Default to snap now days well all mozilla products even installing from terminal/apt/deb you get it as snap still firefox, mozilla etc and this is just a start core is snaps and desktop moving as snaps with kernel and drivers as snaps already on ubuntu core and moving more to normal desktops all snaps and immutable is separate but all is snaps and android like system
i dont say i hate it or dislike it i actually like the idea on it and how they building immutable and how all this structure can change how to build especially atomics and DE yes for now it is only cannoncila and ubuntu, but if they make this working as they has been wanting it will change how stuff will work since everyhting is on small containers/sandboxed as android like and you can change those easyly on mutable systems
ets say you have latest ubuntu with gnome desktop and you want to kde desktop so you just change desktop snap kde from gnome
My point was that it isn’t “brave” to have Mozilla distributing Firefox and itsn’t “brave” to enforce snaps on users who cannot opt out. I insist, users cannot opt out, they can drop Ubuntu and move to Debian. It is just decisions that are mostly lead by corporate/business logic.
Long ago I worked in a place where we had individual roaming profiles so you could sit at any workstation and you got the stardard set of software and access to the remote hosting with versioning and so on. Problem was at any given time there was some developer who needed some tool that wasn’t part of the “standard set” or needed to test some other stuff from external sources. So we had to build “special” workstations that were not under the “roaming profile” system, with all the consequences in terms of syncronization. After some time we had as many “special” workstations as “standard” ones. The alterntive was to include all the “special” conditions into the “standard”, that again made no sense.
Now the thing about “atomic + self contained packages” is obviously meant for a corporate environment where you don’t want the employee to make any change to the read-only part of the system. It is the last thing you should want as home or small business user. Or even in firms where you manage a very different set of services/products.
