Performance Monitoring tool for Android
PerfMon is a "floating" performance monitor tool. It shows on top of any other app you are running. Aside from being useful for powerusers wanting to know what their device is doing, it is a great tool to use during debugging and profiling.
PerfMon will also show you a new and unique-to-PerfMon performance metric: "CPU Capacity Usage". 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.
