Android Studio includes a graphical front end to Simpleperf, documented inInspect CPU activity with CPU Profiler.Most users will prefer to use that instead of using Simpleperf directly.
If you prefer to use the command line, Simpleperf is a versatile command-lineCPU profiling tool included in the NDK for Mac, Linux, and Windows.

Simpleperf tips and recipes
Nuance pdf free mac download. If you are just starting out with Simpleperf, here are some commands that you may findparticularly useful. For more commands and options, seeSimpleperf command and options reference.
Find which shared libraries take the longest to execute
Android Ndk R10e
You can run this command to see which
.so
files take up the largest percentage of executiontime (based on the number of CPU cycles). This is a good first command to run when startingyour performance analysis session.Find which functions take the longest to execute
https://newgospel532.weebly.com/asmedia-usb-30-extensible-host-controller-driver-issues.html. Once you have identified which shared library takes most of the execution time, you can run thiscommand to see the percentage of time spent executing the functions of that
.so
file.Find percentage of time spent in threads
Execution time in a
.so
file can be split across multiple threads. You can run this command tosee the percentage of time spent in each thread.Find the percentage of time spent in object modules
After finding the threads where most of the execution time is spent, you can use this command toisolate the object modules taking the longest execution time on those threads.
See how function calls are related
A call graph provides a visual representation of a stack trace that Simpleperf records during theprofiling session.
You can use the
report -g
command to print a call graph to see whatfunctions are called by other functions. This is useful to determine if a function is slow byitself, or if it's because one or more of the functions it calls are slow.Download Ndk Android Studio
You can also use the Python script
report.py -g
Download hbo go on mac. to start an interactive tool that displaysfunctions. You can click on each function to see how much time is spent in it's children.Profiling apps built with Unity
