Rendering speed has long been a debatable matter and we all know there’s no completely fair and accurate method to discover the fastest browser. However, there are some tests which can be seen as the most relevant tests to see which engine is the most efficient at rendering pages, thus which one can be considered as the most efficient for your daily browsing.
To ensure fairness, the results were taken on the first visit, so we are not mislead by cached pages. Here we go …
Safari 4 Beta: 1) 1.62; 2) 60 ms; 3) 6ms
Internet Explorer 8.0.6: 1) 3.66 s; 2) 599 ms; 3) 14 ms
Mozilla Firefox 3.0.10: 1) 3.26 s; 2) 170 ms; 3) 35 ms
Mozilla Firefox 3.5: 1) 3.80; 2) 47 ms;
Google Chrome 2.0.172: 1) 2.11 s, 2) 22 ms; 3) 11 ms
Google Chrome 3: 1) 3.52 ;2) 16 ms
Opera 9.64: 1) 2.25 s; 2) 224 ms; 3) 6 ms
Opera 10 Beta 1: 1) 2.27 s; 2) 226 ms; 3) 7 ms
Other than that, I am really surprised by Chrome’s speed with the JS. I remade that test on several computers, all in the first run. Apparently Chrome is not only using few resources but it also uses them extremely efficient so even poorly written JS will still perform well on Chrome.
Between Firefox and Opera things look like a tie. Opera was better with HTML rendering while Firefox did well with JS rendering. But overal both were nothing else than average. Not good, not bad, just average.
UPDATE: Firefox 3.5 with very minor improvements, while Chrome 3 came out with some caveats unfortunately.
I will not comment on the rendering of CSS test due to the doubt surrounding it.
Considering the standard ACID 3 test results (found here), I can say that Safari 4 and Chrome 2 can easily take the browser crown (and share it).
