Browser Speed Comparisons

Firefox and Opera make tabs quicker than IE.
...is that a motivated user can compile an optimized version or download an optimized build.
That option certainly isn't available in IE or Opera.

Is "not faster" a euphemism for slower?
To say that my camry is not faster than a porche 929 is a true statement when interpreted one way, but untrue when interpreted another. The use of amphiboly to lead someone to an erroneous conclusion is only different from an outright lie its craftiness.

Interesting results. Firefox may be slower at rendering than IE and Opera, but I love the Firefox extension that disables auto-running flash elements in a page. For whatever reason, my work computer locks up on certain flash pages and this was a huge help.

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.
Really impressive work by that tester tho.:-)

But aren't later versions better, more capable, more adverse-effects resistant?
Also, a browser can render much more quickly if it doesn't care how badly it renders what you see. How does this balance with the loading times in the article?
Can we get a realistic test? Lets see how quick IE is after a couple of days browsing some of the.... less family friendly websites. Firefox would rape it hands down.

I recently switched to Firefox and on NTBugTraq last week, 3 exploits were announced with status of patched. I ran check for updates on firefox and reported nothing. I check A noticed a bunch of other vunerabilities that say patched yet firefox.exe says there's no updates. I went to mozilla.org and even the default download is to the original 1.0 build. What gives? I'd expect update to actually work, there's no way i can install firefox on my parents machines because the only way they actually apply patches is when windows update actually downloads and prompts them. I can tell my parents to find the buried update feature and run it everyday, and that doesn't even seem to work.

Unfortunately, this meant rolling back to Internet Explorer. While I personally prefer Opera, most of the users agreed that Internet Explorer did the best at talking with the internet after this experiment.
Try not. Do or do not, there is no try.

We recently had heard in the office over one of the Yellow Machine that's made by Anthology Solutions.
There doesn't seem to be an allowance for correctness of rendering and conformity of the javascript implementation. If you discard all requirements for rendering and outcome of the script, cat(1) is the fastest browser hands down. Which explains Opera's performance; Opera's rendering and scripting off by just the tiniest bit in every conceivable feature. There's a definite speed/correctness tradeoff and Mozilla has always opted for correctness when practical.
From the article:
Surprisingly, Mozilla is now faster at most tasks than Firefox.
Again, I ask--what exactly is the point of Firefox these days? When it was being billed as the replacement for Mozilla's browser, it made more sense. But Firefox is neither faster or slimmer than the official Mozilla browser, and now it seems it's actually slower too!
I'm just curious what the incentive is supposed to be to use it over Mozilla.
For my browser choice, a few fractions of a second rendering doesn't make me feel warm and fuzzy. I get my cyber jollies from using a browser that has the least number of vulnerabilities. Afterall, those few milliseconds don't add up to the all the down time you might otherwise be stuck with.
I might know what I'm talkin' about, but then again, this is Slashdot...
From the article:
The Moox Firefox install is actually slower than the standard Firefox versions distributed from Mozilla.org, even though it is supposedly optimised for my particular processor.
Or one could say "Firefox beats Internet Explorer in the slowness category". That should pass the Slashdot test.
I tested browsers myself a while back with Stopwatch, and I found Firefox to render consistently faster than IE6. I collaborated with others on the test, and we found that overall, Firefox was about 25% faster. There were some exceptions to the rule though... (most notably, mozilla.org rendered faster in IE. But Microsoft.com rendered faster on Firefox).
I honestly don't know what this guy did differently to achieve opposite results.
This has been popping up on del.icio.us/popular for a while now:
Speeding up Firefox the right way.
This page contains detailed tips about getting the fastest firefox experience, customized to different speed computers and network connections.
What is the point of this? I thought browser speed just didnt matter anymore, at least it doesnt to me. Does anyone even notice rendering anymore? I dont use a computer slow enough, nor have internet fast enough (only a T1) to notice any damn difference. This might have been interesting in the ancient slow days but anymore? come on?
And just how do you test a cold boot of IE? reboot the computer? And if your not using windows why would you ever shut off your browser?
Each intermediate page must be allowed to load completely ... This means that any indicators that the browser provides to show that the page is loading must show the page as loaded before navigating to the next page.
If you read this, you'll know that these benchmarks are mostly useless. How many people wait until a page is completely finished loading before looking at it or clicking links?
Users will tell you that Browser A "feels" faster than Browser B. This doesn't mean that A downloads and renders the entire page faster than B. It means that A displays the necessary content faster than B.
I don't care if it takes 2.5 seconds to load a page if I can see 75% of the content after 0.6 seconds.
Who cares when the progress bar disappears?
There are a bunch of things I'd have done differently when doing a report like this.
The most important one is trying to measure something as close as possible to the Web browsing experience. That means loading pages over a network (at 56K, DSL, Cable, and/or T1 speeds, with some latency) rather than from local files, and loading pages that look more like a random sampling of Web pages rather than constructed examples (e.g., a page with tons of absolutely positioned elements). When the author of the test constructs examples like those used here for the "Rendering CSS", "Rendering Table", "Script speed", and "Multiple Images" benchmarks, the results will have a bias (relative to average performance browsing the Web) towards one browser or another. I'm not saying the author of the tests chose to bias it in a certain direction; merely that constructed tests like this will always have some bias. When such tests become widely used by the press (as iBench has), it even leads browser makers to optimize for the tests rather than for what matters for users.
Also, when testing startup times on Linux (especially cold startup), it makes a huge difference whether starting in a KDE (QT-based environment), GNOME (GTK+-based environment), or other environment, since it affects which shared libraries are already in memory. Testing Mozilla's startup times under GNOME (especially if using a GTK2 version of Mozilla under GNOME 2, or a GTK1 version of Mozilla under GNOME 1) would have improved its performance significantly.
Finally, Mozilla 1.8 hasn't been released yet, so I'm a little puzzled how it was tested. The released version will have changes from the current development version, so it will perform differently. It may be a slight difference, but the report should really say exactly what is tested.
Few people (mainly those in libraries/'net cafes, and privacy nuts) use a "clean" browser. Most people will have hundreds, often thousands, of links in their browser history, tens of megabytes in the cache, a big collection of bookmarks, and plugins like Flash and toolbars. In my experience, a browser will be nice and snappy fresh out of the box, but after a few weeks of piling these things on, it may slow significantly, either in its startup time or while browsing. Some browsers may be worse than others in this regard. The author of the linked article has done an outstanding job, but since it appears most of the tests were performed on freshly-installed, "clean" browsers, the results should be considered with caution.
than the "normal" version?
From TFA:

Firefox 1.0 (Moox):
20.33,2.78,3.18,1.57,26,2.84,41
Firefox 1.0:
11.54,2.52,1.81,1.48,23,2.05,41
Can anybody explain to me? The "unoptimized version" performs better than the optimized one?
O_o
You're right, obviously something's wrong here. Somebody please give the guy the REAL optimized version.
I would actually like to see a comparison of a P3 optimized Firefox (Moox) against Opera. My guess is that Opera uses speed optimizations for higher end processors that would not be available in the vanilla distro of Firefox.
Another question is, did they test the free "Adware" version of Opera or did they use the $40 "Commercial" version (I know Opera 8 was the Beta, so that one is obvious)?
I would personally like to see if Firefox could beat Opera with processor specific speed optimizations and some fairly standard performance tweaks to the about:config...remember, these optimizations would not be available on Opera...
I would also like to see how the much used Adblock extension slows down or speeds up Firefox in rendering some basic pages.
I'm trying to get into the habit of sending letters to sites complaining that they don't work with Firefox or Mozilla. I figure if more people take their business away because they have useless IE-only pages, they'll be forced to revisit these ill-considered decisions.
The same thing is even more true for those sites with popup messages: "This site only works with Internet Explorer." Fix your damn site -- don't blame me for your stupid decision to hire VB programmers.
Hell, even microsoft.com is perfectly usable with Mozilla and Firefox. I certainly haven't noticed a "lack of richness in my browsing experience" there.

Are you thinking of Microsoft breaking TCP/IP to 'fake' faster speeds of IIS and IE? It works like this: Normally when an HTTP session ends, the TCP/IP connection is torn down by the server, which according to TCP/IP standards, involves two packets: a "disconnect request" (sent by IIS or Apache to the browser) and then a "disconnect acknowledge" (sent by the browser back to the server to acknowledge that the disconnect was received. When the client receives the "disconnect" it sends the ACK and closes up the socket on its side; when the server receives the "disconnect ACK", the connection is fully closed and the resources it uses are freed up on the server side. Under normal conditions, if the occasional ACK happens to get lost, then all that happens is that the TCP/IP socket remains open for usually about another two minutes until it times out from inactivity and gets cleaned up by the OS anyway (if you "netstat -a" you should see these hanging around for a little while).
Now, Microsoft did two things: they modified TCP/IP when in conjunction with Internet Explorer to not send the disconnect ACK, and they modified IIS to not wait until it received the ACK to close and free up the socket, but rather to close it and free up the associated resources immediately. This perversion of the very open standard on which the Internet was founded has the following effects:
This whole rather unethical bit of sliminess was primarily concocted to not only make IIS artificially appear faster during benchmarks, but to artificially slow Apache down (because Microsoft was getting frustrated that IIS was unable to kick the Linux/Apache servers' asses).
Ok so I haven't read the article, but from the disclaimer, it doesn't sound like it's possible to make a fair test. What I mean, is that IE is EMBEDDED in windows. IE loads when you open windows explorer, or "My computer" or whatever else file-viewing window it's IE behind it. So there are no real "cold starts" for IE. So that's my first comment on comparing "cold starts" and "hot starts". Second, Firefox shows much more speed on a linux platform. I don't know if that's because I'm running gentoo with a bunch of USE flags to speed up and prelink on top of that, or if it's just because it's linux. Now on the other hand, there's no IE for linux (thankfully!!!). Besides, most users are concerned not about rendering pages but about connection speed and features of their browsers. Not the speed on the machine. Only at work or in a college dorm will you have a connection that could make those speeds perceptible to the user. So, next, comparing Opera to Firefox. Great. Whatever happened to the saying "don't look at gift horse in the mouth?". Opera is not free. Firefox is. Why would you compare something free with something you want a better quality from? It's fine if you want to determine whether it's worth spending the money on another browser, but then you're looking at features, not at speeds. After all, if the whole of the industry wanted lots of speed from their systems, they'd all have dual processor machines running a linux-smp enabled kernel, with blackbox only, right? So, while it may be interesting to compare the ALGORITHMS behind it all, it's not that interesting to me to compare actual speeds, because they're going to vary by environment, machine and user. Someone who has several apps open in the background will notice everything slow down a bit, when someone who only browses without popups will find it more responsive, at least for local operations. Just my $.02 worth.
---- I am certain of only one thing : I know nothing else.
Could the point be that Opera is closed source?
