I think is you who is confusing apple and oranges. at first time, a check of my iphone shows that more than half of the apps I use are bigger than 30m (and 30% of them are regularly 50m and more… I even have apps 500+)… and those applications are the ones that I use the most. no games there. They are: fb, mail, whatsapp, keynote, etc. (ah, no… there is a sudoku there.. 60m :P)
Now… size occupied is not the same as size in memory. This is the size occupied by all app (binaries + data) and I don’t really know of how much that would be for real (I know facebook eats a lot)… Pharo, in the other side, is not using regularly (in iPhone) more than 32m when executing. That’s because you are not loading all image in memory, you paginate the loading (and Mariano’s phd demonstrated that you usually does not use more than 20% of what is inside your image, so most frequently you do not load it completely at all). For DrGeo2 I needed to expand that memory to 64m, but it was still in the reasonable numbers. Now, for distributing your application your image will be not equal to your development image. You will strip things and reduce some others (there is a shrink process that Pavel does in the Pharo-minimal image and time ago I made some experiments and I ended with an usable 8m image running in iPhone… I even got a 4m image but no morphic was present so it was using ObjectiveCBridge to show some screens with functionality…) Also, for production you will be removing sources and changes, so you do not have to take those into account (even taking it, they are never loaded into image, they are accessed when needed). So… I think a mobile final app of 20m - 50m (and take into account that a 50m app will be really big, DrGeo2 was 35m) is perfectly reasonable. Is not huge and most applications nowadays (even the stupid ones) occupies way more. Now, that 5% idle is much-much more worrying that app size. And we already have an even VM who does not consumes that (JB did it) It will be integrated soon (JB needs to finish I don’t know exactly what). Esteban > On 25 Nov 2014, at 16:58, Esteban A.
