I thank you for your attention, and I am very happy that you found this article interesting or useful enough to read. Browsers compete on many fronts; security, standards support, features and speed. Most. people are aware of which major browser fails on three of these, but one of them is still open for grabs.
Speed. Many organisations and users try to claim that their browser is the fastest. Mozilla itself is quoted as being an alternative. Microsoft IE and it's faster to boot. Apple's Safari pages claim that Safari.
Mac web browser (although they failed to show any results for Opera, and their. Internet Explorer users often claim that they use it because of. Opera and Firefox users are quite vocal on the subject. Those. that did try more than one usually say .
I have even heard people comparing. Firefox and Opera, then realised they were referring to Opera 6 (even though historically, Opera 6 is about equivalent to. Netscape 4), something that was replaced with a completely new engine long before Firefox even existed. Well, I've had enough of these unfounded arguments.
I present my research. This is an honest, unbiased view (or as unbiased as I. Unlike most people, I not only test all the browsers, I test them all on the same computer as each other - grouped.

And please, those of you whose browsers did not perform as well as you had hoped, just accept it. Stop. with the comments saying this article is biased. It does not matter what I use or you use.
This article is not biased. The fastest. browsers are the fastest browsers. I appreciate browsers for the sake of them being browsers. I feel no need to tailor tests or. The tests. In order to test each browser's speed response, I put them through a number of tests. Each test has a careful set of rules.

The idea was to find out the fastest browser(s) at performing the major tasks that browser engines are expected to perform. Obviously nothing can be perfect. But they do give a very good idea of how each browser would.

Small variations in hardware or software can cause big differences in results so it is important. After logging out and logging in, I load a browser, clear its cache, enable. The tool tests a good variety of different things, including mathematical calculations.

Media multitaskers pay mental price, Stanford study shows. Attention, multitaskers (if you can pay attention, that is): Your brain may be in trouble. People who are regularly bombarded with several streams of electronic information do not pay attention, control their memory or switch from one job to another as well as those who prefer to complete one task at a time, a group of Stanford researchers has found. High- tech jugglers are everywhere – keeping up several e- mail and instant message conversations at once, text messaging while watching television and jumping from one website to another while plowing through homework assignments. But after putting about 1.
They’re suckers for irrelevancy,” said communication Professor Clifford Nass, one of the researchers whose findings are published in the Aug. Proceedings of the National Academy of Sciences. The brain just can’t do it. But many researchers have guessed that people who appear to multitask must have superb control over what they think about and what they pay attention to. Is there a gift? So Nass and his colleagues, Eyal Ophir and Anthony Wagner, set out to learn what gives multitaskers their edge. What is their gift?“We kept looking for what they’re better at, and we didn’t find it,” said Ophir, the study’s lead author and a researcher in Stanford’s Communication Between Humans and Interactive Media Lab. In each of their tests, the researchers split their subjects into two groups: those who regularly do a lot of media multitasking and those who don’t.
In one experiment, the groups were shown sets of two red rectangles alone or surrounded by two, four or six blue rectangles. Each configuration was flashed twice, and the participants had to determine whether the two red rectangles in the second frame were in a different position than in the first frame.
They were told to ignore the blue rectangles, and the low multitaskers had no problem doing that. But the high multitaskers were constantly distracted by the irrelevant blue images. Their performance was horrible. Because the high multitaskers showed they couldn’t ignore things, the researchers figured they were better at storing and organizing information.
Maybe they had better memories. The second test proved that theory wrong. After being shown sequences of alphabetical letters, the high multitaskers did a lousy job at remembering when a letter was making a repeat appearance.“The low multitaskers did great,” Ophir said.
If the heavy multitaskers couldn’t filter out irrelevant information or organize their memories, perhaps they excelled at switching from one thing to another faster and better than anyone else. Wrong again, the study found. The test subjects were shown images of letters and numbers at the same time and instructed what to focus on. When they were told to pay attention to numbers, they had to determine if the digits were even or odd.
When told to concentrate on letters, they had to say whether they were vowels or consonants. Again, the heavy multitaskers underperformed the light multitaskers.“They couldn’t help thinking about the task they weren’t doing,” Ophir said. They can’t keep things separate in their minds.”The researchers are still studying whether chronic media multitaskers are born with an inability to concentrate or are damaging their cognitive control by willingly taking in so much at once. But they’re convinced the minds of multitaskers are not working as well as they could.“When they’re in situations where there are multiple sources of information coming from the external world or emerging out of memory, they’re not able to filter out what’s not relevant to their current goal,” said Wagner, an associate professor of psychology. By doing less, you might accomplish more.
