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!

PSA: You Can Optimize Your Note 4’s Recents Menu & RAM

The Note 4 never had the fastest Recents Menu, and despite its 3GB of RAM, its app-holding capabilities only got worse on Lollipop. The infamous RAM bug that plagued the S6 is indeed an annoyance on the Note 4's 5.0.X ROMs. Rumors of an update to fix all of this were confirmed with the first reports of the 5.1.1 update for the Russian Note 4, which seemingly improved the Recents Menu and RAM management. But it'll be a long time...
