    I suppose the fact that IE has all sorts of nice direct access to the Windows code with god-knows-what tricks embedded to speed it up helps. Firefox is bound by what any non-MS program can do with the API.

    That is not to say that I find Firefox slower - but thinking about it, I believe the Firefox interface (especially tabs and yes I know it was Opera first(?)) speeds _me_ up. So my perception is that using Firefox is generally faster than using Internet Explorer, even though it may be in actuality slower.

  13. Not really surprising to me... by Jugalator · · Score: 2, Interesting

    IE is a slimmed down browser where I can imagine its rendering engine simplicity combined with Microsoft's unique experience with the Windows kernel and the integration makes for a fast browser.

    Opera seems to be a minor miracle in terms of code optimizations, at least on the Windows platform, since it's not OS integrated or cheats with pre-loadings, and the Opera team lacks Microsoft developers with knowledge about undocumented API calls, etc. Still it usually beats IE hands down with a vastly superior rendering engine, on par with Gecko. It's only unfortunate it's ad supported and closed source.

    Finally, Firefox/Gecko is a very nice open source browser with nice extension support, but building on the cross-platform UI toolkit XUL instead of using native widgets, along with being built for platform independence instead of being heavily optimized for various platforms (I imagine the Opera team has to do more work for their browser to work on other platforms). I think some of these things play a role in some of Firefox's speed issues. There's no problem with the code I think, just a side effect from what Mozilla is trying to accomplish with the code.

    It would've been interesting to have him compare to K-Meleon or Galeon as well, since it's slimmed down to the bare bones Gecko layout engine with just minor stuff in addition, and that stuff is also using native widgets AFAIK. Might have a positive effect on the loading times at least.
