Want your iPhone 4 to run faster? Install iOS 7.1

Good news for iPhone 4 owners: Apple's iOS 7.1 update, released earlier this week, should make your handset feel a little snappier.

The bad news: It still won't run as fast as it did on iOS 6.

So writes Ars Technica, which conducted basic iPhone 4 performance tests with iOS 6.1.3, iOS 7, and 7.1. Specifically, the blog clocked load times for various stock apps like Camera, Messages, and Mail, and also the time to complete a cold boot.

The results: iOS 7.1 boots a bit more quickly than iOS 7 (43.1 … Read more

Google modernizes Octane JavaScript speed test

Google has updated its Octane speed test for measuring JavaScript performance, expanding its scope and rounding out the benchmark with computing tasks from rival browser makers Mozilla and Microsoft.

With the expanded scope, Google tries to measure not just execution performance but also delays that can trip up Web pages and Web apps, Google said in its Octane 2.0 announcement Wednesday. Specifically, it added new tests to gauge sluggishness from the initial compilation of JavaScript programs into machine-executable code and from the memory-scrubbing operation called garbage collection.

Why your next Android tablet will be more powerful

Your Android tablet sucks. At least compared with what's coming. Later this year we'll see the release of three new Systems on Chip (SoC). SoC is simply the name used for the collection of silicon that makes up the brains of the tablet and includes the CPU, GPU (graphics processing unit), onboard memory, and other processors.

The new chips will no doubt be used to power many high-end Android tablets and are expected to deliver better-looking games, faster Web surfing, increased battery life, and in at least one case, could allow you to take better-looking photos.

Of course, … Read more

There is just no substitute for bandwidth when it comes to Internet speed. Whether it's water or data, the principle is the same: the bigger the pipe, the bigger (and faster) the flow. But that doesn't mean there's nothing you can do on your end to improve your online experience, especially if you're one of the many users still running dial-up connections. If you're trying to squeeze every bit of performance out of your Internet connection, you may want to have a look at Throttle. Throttle offers to maximize your PC's network settings, whether … Read more

GameGain Review

If your computer can't keep up with your games, it may be time to give it a boost. For a small fee, this program wants to change a few settings on your computer to make things run faster. Sadly, the GameGain trial version doesn't make good on its promises; you won't notice any performance upgrade in any of your favorite games.

The program offers a free trial that lasts for 29 days, while the full version costs $12.99. You can't unlock GameGain's "fastest" setting" without paying up, though. The program occasionally … Read more

Speed up your gaming and Internet experience with GameBoost

Is your older computer struggling to keep up with the latest and greatest games? GameBoost claims to save you from having to boost your hardware by giving you more performance through software tweaks. However, any changes the trial version makes aren't noticeable at all. In fact, the program doesn't boost your computer's power or speed one bit.

The trial version of the program offers most of the performance tweaks for 29 days. The "fastest" performance upgrade isn't available unless you buy, though. GameBoost requires some administrator access to work, which makes you think it … Read more

Older and slower systems will get the biggest PCBoost

We've seen plenty of tools that promise to boost your PC's speed, but like the proverbial bear in the woods, some do and some don't. PCBoost promises to boost your PC's speed, too, and it has some options and displays that can help you do that, up to a point. It's shareware, though you can try it for free for 30 days. It's affordable, but it doesn't do more than many free system optimizers, and actually does less than others. It claims to exert control over how your PC prioritizes processor resources, "… Read more
