Android 2.2 packs 5x performance boost, says report

A Website claims it tested the upcoming Android 2.2 software and is seeing a 450 percent performance gain over Android 2.1.

Full Flash support may be Android 2.2's most noteworthy feature, but the update known as "Froyo" could pack a wallop for other applications as well.

Android Police claims to have Android 2.2 running on Google's Nexus One, though it's not clear how it obtained the software. The blog didn't talk much about features, but instead got right down to testing Froyo's performance, and discovered improvements of up to 450 percent over Android 2.1.

Android Police used a benchmark called Linpack, which measures performance in millions of floating point operations per second, or MFLOPs. Testing generally reflects the state of Android's Dalvik Virtual Machine, which is responsible for executing applications.

Testing revealed a Linpack score of 37.6 MFLOPs in Froyo, compared to 6.5 or 7 MFLOPs in Android 2.1. That's a 5x improvement, the implication being that Android games and apps will run several times faster than before.

The reason for performance gains is likely due to Android 2.2's use of just-in-time compilation, which speeds up Javascript by compiling it into native code right before execution instead of running everything through an interpreter.

Android Police notes that the speed boosts may not have a direct impact on Flash performance, because Flash will probably be compiled to native code already, and therefore won't need just-in-time compilation. However, boosting performance elsewhere clears more resources for Flash, so the benefits could be indirect.

Google hasn't confirmed any details about Android 2.2, except Flash support. Rumored features, as mentioned at AndroidandMe, include FM radio, color trackball notifications, additional free RAM, enhancements to OpenGL ES 2.0 and other stability fixes. Answers will probably come on May 19 and 20, during Google's I/O conference for developers.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
