"Just purchased this affordable app, and only a moment later I am seeing wi-fi traffic throughput not unlike the Windows AnalogX and SysInternals suites of system monitoring applications. Even PerfMon is not as intuitive as this. A+"

"It would be great if the developer would update this app since it`s been almost 2 years. Several updates and a major version of Android since last app update. . (1) I was never able to see the Disk I/O window work at all on Samsung S6 Edge or newer Samsung device. It never hooked in. Wifi connection stopped showing up with Nougat as well. . (2) It would be nice to be able to set opacity for all 4 windows and have the title bar for each also take the transparency/opacity setting to prevent burn-in on these amoled screens. Mine burned in one of the windows as I always placed it in the same corner."

"Honestly, the kind of performance/task manager that could in practical terms, preceding the release of this mini suite, only be found on a windows class machine. From features on through functionality & all that before taking into account the entity of monitors can be simultaneously positioned whilst visibly operable in transparent windows communicating detailed specifications in real time.

"But why not develop a bit further? Or no? Last update a year ago. I do agree that the overbloating is counter productive. Simplicity is what makes this app so great. And thanks for fixing that pop up ``to buy the app`` when already bought it."

"The floating monitors are promising but they`re always in the way and they`re too opaque. Limited to foreground/visible task makes it kind of a gimmick or proof-of-concept. If we`re trying to see an elusive resource hog in action, it`s not usually foreground/visible. This has promise, but it needs more intelligence. Unfortunately, it appears the app is no longer being enhanced."

DESCRIPTION
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 offers you four categories of metrics:

- Foreground App
- CPU
- Disk I/O
- Network I/O

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.

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

--- Foreground App ---

This window shows metric of the currently foreground (running and visible) application:

- Application title
- Application package name
- Memory usage total (in megabytes)
- Dalvik, Native, and Other memory usage (in megabytes)
- Overall CPU Usage (normal percentage and capacity)
- User and System CPU Usage (normal percentage)

--- CPU ---

This window displays overall CPU metrics:

- Capacity usage and current divider
- Overall CPU usage percentage
- Per-core CPU usage percentage and megahertz

--- Disk I/O ---

This window displays the disk I/O metrics of your MMC-based storage devices. Usually, mmcblk0 is your internal flash, and mmcblk1 is your removable SD-card. Please note that currently MTD-based storage is not supported by this display. Also note that the metrics displayed are raw I/O, so if the OS has I/O requests buffered/cached, you will not see anything happen here.

- Per-device read and write kilobytes/second

--- Network I/O ---

This window displays the network I/O metrics of your network interfaces.

- Per-interface transmit (Tx) and receive (Rx) kilobytes/second
