So you see, all changes when you open anything.
In P990 when opening mail, from 10,5MB free
6,4MB is left.
woah..this is bad. That's 4Mb. My N95 used up 2Mb to open an email (this incl. the activation of WIFI connection). Now I see why it is more crucial for p990. SE should "un-bloat" the Messaging app.

Yes ! Whether or not this relates to demand paging, it's an enormous memory footprint, for an essential communication app !
Not related to messaging content BTW - I keep a very lean inbox : have deleted all my emails, 23 sms's in inbox only. And it still consumes 3MB (64.8 ->61.8 currently)

So I'm just saying "this is not a fix- all". And I would dearly like to see something a bit more rational come up if people are serious about pushing SE to not abandon firmware- development for the p990/w950/m600 than "we want demand paging, because that worked on Nokia, and SE is just too lazy to backport a SOLUTION, even though they know it works!", etc.
Ok?
And...just what were we arguing about? These are what I've been saying all along. Considering that it took a huge uproar to get SE to correct some major bugs in the final P990 fw, I'm willing to take any bet that SE will do absolutely nothing to improve the P990.
One more thing I would like to point out is that both the Nokia and SE are based on the core Symbian OS. S60 and UIQ3 are user interfaces that run on top of this OS. Demand paging has to be implemented at the core level OS (level 2 or 3 of the OSI), so I'm wondering if Nokia did this themselves or had Symbian do the work. If the latter case is true, it would make SE's job easier but since SE has no intention of doing this it's a moot point anyway.
Communication by writing alone can be misinterpreted at times, so @Nipsen, I didn't mean to offend you, I guess we can all get carried away in the heat of the argument.

Level 3 memory reclaim: 11.2 MB free RAM (uptime 7 days)
Open messaging: 7.1 MB (16 SMS, no email messages)
Terminate messaging using SMP: 9.9 MB
Reclaim memory: 11.3 MB
Talk about bloated sw and memory leak !!!

And aqualung, I respect what you have done with the open letter. But as I said, you won't have the opportunity to get both long battery life and stability, as well as a work- around for the ram. Neither does it suit anyone all that well to berate SE for not "giving" you the impossible.
But seriously, this is not worth it. If it makes you happy, believe what you want, and make up whatever "facts" you like. But I guess I can see why SE hasn't exactly jumped to the aid of the p990 users before, if this is the kind of frayed thinking that hides behind the self- righteous criticism.
@Nipsen
I never asked for long battery life
as I said the main issue for most P990's is free RAM.
You've obviously never had the pleasure of owning a P990. I dare say most P990 owners would be willing to take a knock on battery life in exchange for extra RAM.....perhaps it's better to canvas their opinion, as IO wouldn't want to be making that "fact" up.
Seems good to me.. I guess I read what you said as meaning you wanted a ram- fix without any performance hit.
(..I'm probably still arguing against the claim in the previous thread: "demand paging decreases boot- time, lowers ram- use, improves battery life by 25%, and gives you free drink at the pub for the next three weeks". Sorry about that)
With all due respect there, it makes you look like you're trying just a bit too hard.....ease up on the verbal abuse OK ?
Nah. ..You know - I'm usually very accommodating. There's literally no amount of stupid I can't take. I mean, what can I say - I think it's interesting to hear people explain things that will never make sense, except perhaps in a different universe, or something that doesn't fit with the explanations I have already.
But. When people consciously redefine the context of their argument, so they can dismiss perfectly sound connections they made earlier on, in order to restate their failed argument again - then we're not talking about "stupid", interesting, or unorthodox any more.

If I remember correctly, the topic was demand paging. When someone claims that it may be beneficial for the P990:
1- Because it doesn't make sense to you doesn't mean it is wrong.
2- The explanations you have may not be the absolute facts.
I am not going to repeat what I have already stated but I find it amusing that you can be somewhat hostile if people do not agree with you.
Without in depth knowledge about the P990 OS (Symbian+UIQ) everything you or I say will be pure speculation - unless you work for Symbian as a software engineer.
