Really Microsoft? Do you really need all the ads revenue from the weather app?
What’s next? Ads on the start menu?
by itopaloglu83 - As time goes on, I become more and more convinced that OSes need some sort of OS level GC pool which all GCed languages play in rather than having the language runtime provide the GC.
A major part of why these sort of simple applications are taking gbs of memory is because the GC wants to simply grow as much as it can to avoid pauses/jank. There might be 10% of the memory which is actually live in that 1gb. But because it allocates fast enough, the extra headroom is needed.
Even if it isn't the case that the GC is universal, having a shared GC amongst runtimes would be a boon in general. If I have 3 JVMs running, I might give them all 1gb of memory even though really each of them only needs 200mb to get their job done. The extra headroom is for when a burst happens. If I could combine all 3 into 1, I could save a lot of allocation overhead and general memory.
This does sort of exist in java (war deployments), but there are limitations that make it unappealing. For example, each of the JVMs have to be the same version.
by cogman10 - This took me down a rabbit whole. Why can a simple single purpose app not be just a couple megabytes if not less? The popular options are electron 100MB+, or embedding python3 in your executable which is at least 40MB.
But if you build it natively, you should have all of Microsoft tools at your disposition, dlls and such. In theory, this should allow you to make a 1 mb app or less. But in practice, it's the worse option.
by firefoxd - They're pointing to macOS and saying it uses 5 times less RAM there, but is 230MB for a weather app really something to be proud off?by ed_mercer
- As embedded guy, sometime i wonder what those web devs are doing. A simple app that consumes multiple magnitude more RAM than the entire system i usually working with(~1MB). I assume it just does some HTTP query and render it on the screen, why the heck 1GB of RAM ?by mrheosuper
- Easy workaround for this:
1. Install uBlock Origin in Edge.
2. Start Edge, browse to MSN Weather.
3. Click the "Add an Application" button in the address bar to get a Start Menu icon for the page.
4. Delete the in-box Weather app icon.
Now you get the same Weather app in about 130MB of RAM, with no ads. It's not as nice as a native app, of course, but it's 1000% better than the useless ads and MSN feed that you can't block from the built-in Weather icon.
(Also, go into Widget settings and turn off "Discover / Microsoft Start feed". Same crap, different surface. Get rid of it.)
by SBArbeit - Putting aside the fact that it is horribly bloated. Accurately measuring RAM usage is tricky, there are several measurements, and no "right" one.
It is clear from the article that what eats up so much RAM is not the weather app itself but the framework it runs on. There is a "Renderer", a "GPU Process",... eating most of it.
The thing that the task manager doesn't tell you is whether or not these are shared components. It may be that the 662 MB used by the "Renderer" is shared between many Windows components, so killing that Weather app may not reclaim as much space as you may hope, instead, it would require killing every user of the component, some may be core system apps.
In addition to the distinction between private and shared memory, there is also the distinction between actual RAM usage and and virtual memory. It is possible for a process to memory map a 100 GB file. If you look at the address space, it will take 100 GB more of virtual memory, even though it may be actually zero physical RAM, but it is not always zero either, the parts of the file that are currently accessed take up some space, which may later be reclaimed by the OS by committing the page to disk.
Even the most obvious "I do a big malloc()" kind of memory use is not that obvious, the OS can overcommit, put stuff into swap, use memory compression, etc... And it can do that even if the system is not overloaded, as to make more space for the disk cache for instance.
So seeing "1 GB" in the task manager is just a vague hint of how it may affect performance. And not all "task manager" tools give the same value for the same program (so Windows vs Mac may be misleading). "Process Explorer", a more advanced version of the Windows task manager can give a lot more details, with different values of memory usage depending on what you are looking at.
by GuB-42 - My gaming PC that I built in January 2006 that IIRC I used to simultaneously run Battlefield 2, Trillian, Xfire, Thunderbird, and Winamp with a 1680x1050 monitor had 1 GB of total system RAM.by ndriscoll
