Hi all,

I've found this blog:
http://blog.meltingice.net/programming/camanjs-benchmark-firefox-4-beta-kicking-chromes-ass

I run the benchmark  http://dev.meltingice.net/canvas/test/benchmark.html 
and found the following results on a Core2 Duo 2.66 GHZ /Fedora 15

all webkit ports are really slow compared to firefox4 :(

              firefox4         Arora0.11.0(webkit 533.3)      chrome (11.0.696.71)    midori(webkitgtk-1.4.0)
