1The case for x64 browsers?

I’ve recently been using Fire­fox 4 64bit pre­b­eta, also known as Mine­field. I thought it would be inter­est­ing to com­pare vari­ous browsers to see if this sup­ports my feel­ing that Mine­field is the fast­est browser I’ve used. The con­clu­sions are quite inter­est­ing. I will con­tin­ue to update this table as new ver­sions are released

Con­clu­sions…

• Mine­field cur­rently crashes when run­ning Peace­keep­er. This should be fixed in the next build.
• Neither Fire­fox nor IE are quite able to com­plete the ACID3 test correctly.
• It seems that Opera has by far the best JavaS­cript engine, but I know from exper­i­ence that its page load times are not good, and I don’t like the way it renders fonts.
• Chrome and Safari are very close in per­form­ance and are the fast­est over­all for JavaS­cript if Opera is ruled out for slow data load times.
• Chrome is fast­est over­all for SVG and HTML5 hard­ware accel­er­a­tion. It is also the fast­est for flash (exc. 64سا), and very close to Mine­field. Once Chrome has full hard­ware accel­er­a­tion it will be indis­put­ably the fast­est (unless Mine­field improves its جے ایس engine by release time)
• انٹر نیٹ ایکسپلورر 8 is a waste of time.
• IE9 is a big improve­ment on IE8, but still lags well behind the rest.
• IE9 x64 is slower than IE9 x86 — a case of poor optimisation?
• It’s now obvi­ous why محترمہ made IE 32bit the default browser in windows.
• فائر فاکس 4 looks to be a lot faster than fire­fox 3.6, but still slower with most javas­cript than Opera (altho the Moz­illa Kraken bench­mark which seems most strenu­ous gives Fire­fox an advant­age. How fair and inde­pend­ent are the vari­ous tests?)
• Hard­ware accel­er­a­tion is clearly the future whenev­er it an be utilised.
• 64bit fire­fox 4 is sub­stan­tially faster than 32bit fore­fox 4 in a few bench­marks, but on par or a bit behind in most. Par­tially this is prob­ably due to the nature of its pre­b­eta status, com­pared to 32bit fire­fox 4 being near final release. It also high­lights that many things do not bene­fit from x64 yet.
• فائر فاکس 4 looks to be the most roun­ded browser at this moment. Hope­fully an offi­cial release of Mine­field will improve upon this. Chrome is a very respect­able second. Once Chrome gets full hard­ware accel­er­a­tion it will sur­pass Firefox
