PerfMon Floats Your Device’s Performance on Screen

In the course of developing an application, or even looking at deploying a new kernel or ROM, it is often necessary to benchmark your changes and see what effect your efforts yield. No one should deploy something that gives your users a negative experience. XDA Elite Recognized Developer and Senior Moderator Chainfire feels the same way, so has added a new application to his repertoire: PerfMon.

PerfMon is a “floating” performance tool, which operates as an overlay to your existing application. It will provide real-time stats for the foreground app, CPU, disk I/O and network I/O. These can be used to see exactly how your application performs in any given situation. It also has a new performance metric unique to PerfMon called CPU Capacity Usage. As described by Chainfire:

The CPU usage percentage traditionally used to measure and compare how much of the computational resources an app (or the entire device) is currently using does not make sense in a mobile multi-core setting. The capacity metric will take the CPU usage and scale it to what it would be if all cores were running at full capacity.

For example: if you have a 1.6ghz quad-core running a light app, it could be using 10% CPU with only one of the four cores active, and that core running at 200mhz. If you translate that to all four cores running at 1.6ghz, that app is using only 0.3% of total CPU capacity.

It’s the only CPU Usage metric that makes any sense!

Chainfire has posted the full version in the application thread, where you can find out more about how this works. He also has a link to the Google Play version, so head over there and provide feedback and support his efforts. And if you haven’t already heard, Chainfire will be at the BigAndroidBBQ so if you want to meet the iconic man, and experience what Willverduzco did, make sure you stop by XDA’s booth and say hello.
