This video has been sitting in my "Starred Items" list for a few days, and I finally got a chance to watch it. Holy cow. If you’re not familiar, Demand Paging is something that was originally planned to be included in Feature Pack 2 of S60 3rd Edition. Demand Paging is somewhat like a virtual memory application, and essentially manages memory alot more efficiently.
Here’s a quick video demonstrating Demand Paging on the Nokia N95 (original version). You can see that it increases bootup times, application load times, and, more importantly, RAM usage. Thus, with Demand Paging, you can open up a massive application such as the phone’s browser, and only use up minimal RAM. Also, more RAM is available after you close the app, as well.
As stated before, it was previously understood that this would only come with S60v3 FP2. However, Steve Litchfield recently stated that the N95 8GB version also features Demand Paging. I’ve also heard reports that the original N95 is due for a firmware update that will include Demand Paging, as well. Time will tell.
