NT -> moves pages from RAM to swap even with 1GB of unused ram -> much slower when trying to access these pieces of data. But still fast enough, don't misunderstand me (maxthon nmay have 50MB of used memory, there's still 350MB of paged data!). When comparing XP with 2k, people did not think "hey, my computer does not have enough ram", but instead started wondering what the hell MS developpers had done with this OS. However, this is getting incredible here. As a part-part-part-part-part-part-time developper, I know that mem usage can grow very quickly when you a GUI (having the possibility to move a bar from top to bottom of the window for example!) I'm sure some people here are comparing usage on 32bits systems with usage on 64bits/32Bits with PAE, without knowing what it implies! nice post mate, its so futile, these topics... everybody uses the browser he can do the most with, and has things he wants in a browser. maxton+IE, great opera, great firefox, great <-- i use this coss of the nice favorite bar, not that firefox is better, its just suited for ME and all 3 are fast, if a warm start of ur browser takes 5sec, is slow, if its 3 or less, its fast... who cares about the 1.8 or the 2.4sec :/ and memmory usage, with 500mb who gives a ***** if it uses 70mb or 120mb :/ but fridge i do a lot of 3d modelling, i need ram yeh but u got 1gig of ram oh yeh thats true
