Linaro Tweaks Speed Up Android, By Up To 100 Percent 97

Argon writes with an excerpt from Liliputing of interest to Android users: "'The folks behind the Linaro open source software project have put a little time into tweaking Google Android to use the gcc 4.7 toolchain. The result is a version of Android that can perform many tasks between 30 and 100 percent faster than the version of Android Google 4.0 Google currently offers through the AOSP (Android Open Source Project).' Adds Argon: "Note that there are CPU optimizations only since they have only access to binary blobs for GPU code."

    I know a busy slashdotter such as yourself can't be bothered to move his greasy fingers the fraction of the inch required to actually open the article and as such here is some information you might find of interest:

    ... and the results are quite amazing with Android Linaro achieving about 60 fps in all 0xBenchmark tests (OpenGL Cube, OpenGL Blending, OpenGL Fog and Flying Teapot) whereas Android stock achieving 30 fps. They selected a benchmark tool that is mainly CPU bound, as they cannot optimize the GPU code since they can only access binary blobs.

    Also as you said yourself, it's a summary if you want the meat and potatoes of the data described just click on the damn thing instead of bitching.

    The cynic in me says that even if it is a simple patch and recompile for existing android devices, we will never see it from any OEMs--it takes away some of the reason to buy the latest shiny.

    Here's hoping for the community android rebuilds...

    The commentators on hacker news seem to be fewer in number and the focus and readership seems to be more about web technologies and startups. I could care less about your new jquery library for styling select boxes (or any reinventing-the-wheel-in-javascript project) and entrepreneurs are mostly failures waiting to happen.

    As far as I'm concerned Hacker News has a higher SNR.

    Taken from Bero's comment:

    Obviously saying we’ve made it “twice as fast” is a bit of an oversimplification.

    This particular benchmark (the 3D benchmark included in 0xbench) runs twice as fast on this particular hardware. Other benchmarks (e.g. Sunspider) are “merely” 30% faster, some others are only slightly faster (e.g. GLMark2 – as it’s mostly GPU bound), and it would be possible to craft a benchmark showing that our build is 10 times faster (write a benchmark that uses strcpy, memset and friends heavily, which I’ve actually done, not to show off but to test if our changes are as beneficial as we’re hoping).

    As they say, the benchmark used is CPU-bound and as such what you're referring to is irrelevant. You can go ahead and test the optimizations made if you feel like, it is all there. A 3D benchmark was only chosen so they have something more interesting for the spectators to look at than a console application or Sunspider.

    In the last screen of the benchmark/demo, you see 4 different tests that are each one individually exactly at 60FPS +/1 FPS for the Linaro build and 30FPS +/- 1 for the stock build... Better not question the coincidence and make a slashdot article about that 100% speed improvement !
