Benchmark Your I/O Performance With Bonnie++ for Android

Ever wanted to use a standard *nix disk benchmark tool with your Android-powered device? If so, XDA forum member saturn_de has just ported the benchmark Bonnie++, originally created by Russel Coker, to Android. If you have ever wondered what effects changing your I/O scheduler have on your disk performance, you should give this a shot!

Available in both pre-compiled versions and source, you are only a few clicks away from finding out just how fast your device is. In the words of the developer:

Now you can test all of your cfq, bfq or whatever IO scheduler with a standard unix benchmark tool. Builds with ndk-build.

Bonnie++ recommends/uses disk space twice as big as your RAM is, although you can circumvent this with “-r 0 -s <size(MiB)>”. So use a partition with more than 1.6 GB space.

Running the benchmark takes quite a while depending on IO speed, filesystem type and test size (~90 minutes).

Continue on to the benchmark thread to get started. Make sure to post your scores while you’re at it to build up a database of device performance!

Best Apps To View RAW Images On Android

Last week, I wrote about the best apps to unleash the raw photographic power of your Lollipop smartphone. All four of those cameras generate lossless DNG images with pounds of potential for apps like Photoshop to unlock, but what if you’re looking to edit or view those pics on the go? QuickPic, Google Photos, and the other mainstays treat raw images like they don't exist. This rundown seeks to fill the void and give you full control over your precious pictures....
