* webkit is known for / designer for very good performance and low memory usage, and is used in nokia S60 phones, the iphone, the latest palm phone (as the basis for WebOS), google android's web browser - you name it, webkit's been there and done that. [it should tell you something that the world's top major smart-phone manufacturers _don't_ use firefox, or they pay for opera] * squirrelfish, the JIT javascript accelerator, has a 32-bit x86 port as well as a 32-bit ARM port. even without this (on a debian amd64 system), a simple empirical use of webkit from august 2008 absolutely smoked firefox 3.0 by a good 2-3 times speed increase, for the large "web 2.0" pyjamas (javascript-only) test apps i was running. * progress is being made to port the use of google's v8 JIT javascript compiler engine into webkit. as is google's habit they throw resources at projects, in this case the google chrome project; the engineers added V8 to _their_ version of webkit, and merging back is taking quite some time. > - Behaviour in non-standard-dpi screens the require scaling.
