"Memory and disk tests were done on a Pentium D system at 3.2GHz with 2GB of RAM, running Windows XP Professional with Service Pack 2 installed
With no pages loaded, and with no bookmarks, and otherwise with default download settings, here was the memory use for each of the browsers:
Memory Usage in MB (no pages loaded)
Firefox 2 Beta 1: 42
Internet Explorer 7 Beta 3: 24
Opera 9.0: 53
IE 6.0: 17
Firefox 1.5.0.4: 17.8
We also tested memory use on the browsers with a bunch of tabs loaded. We used the same group of tabbed pages on all of the browsers—ExtremeTech home, Yahoo, PCMag.com, YouTube, BBC World, and Flickr (with the same picture showing). With this tab load the results were as follows:
Memory Usage in MB Loading Six Tabs
Firefox 2 Beta 1: 73
Internet Explorer 7 Beta 3: 70
Opera 9.0: 52
IE 6.0: 155
Firefox 1.5.0.4: 56
Disk usage for each was as follows:
Disk Usage
Firefox 2 Beta 1: 18.8MB
Opera 9.0: 20.7MB
IE 6.0: 1.9MB
Firefox 1.5.0.4: 18.6MB
None of this would tax a reasonably updated machine. And keep in mind that the beta products will most likely improve in efficiency before final release as a result of code profiling. The low IE6 size can be explained by that program's reliance on code already in Windows."
Vagy lásd ezt a tesztet (ez is elég részletes leírást ad).
"szöveges böngészõk jók lennének de kezeljék a mai kor elvárásának megfelelõ dolgokat is, pl. Flash"
A Flash, mivel nem szöveges állomány (illetve nem sokan használják ki a szöveges tartalom elérhetõségét) nem igazán tud mit kezdeni vele (esetleg letöltheti, amit stand-alone lejátszóval futtatsz).
A másik sarkalatos pont a Javascript, ahol megint csak problémát okoz a grafikai effektusok tömkelege.
