stress is a simple package to put pressure on CPU and IO in various and multi-threaded ways. Originally developed by Amos Waterland, the added value here is the Android.mk file that lets you add it to Android AOSP to build. This is not an Android Java program, but a bare command line tool. To execute it, you need access to a shell terminal. You may need to have root access to push it in /system/bin directory.

ndk-build

adb shell mkdir /data/tmp

adb shell chmod 755 /data/tmp

adb push obj/local/armeabi/stress

You can see the program's usage statement by invoking it with --help. A typical invocation is:

stress --cpu 8 --io 4 --vm 2 --vm-bytes 128M --timeout 10s

A user manual is available:

info stress

This program works really well for me, but it might not have some of the features that you want. If you would like, please extend the code and send me the patch. Please use the context diff format. That is: save the original program as stress.c.orig, then make and test your desired changes to stress.c, then run `diff -u stress.c.orig stress.c' to produce a context diff. Enjoy the program :-)
