See more: Embedded C performance
I am adding a new protocol to the existing embedded system on ARM cortex processor. I need to do a load test and performance test after adding the new protocol to earlier
system. The source code is in C and C++.

Please let me know if any free test code to do a load and performance test, network
I/O test etc on this embedded system. Or suggest me any methods for this.

Basically I have to compare:
1. What is the load after adding the new protocol.
2. Performance
3. Network IO tests
4. System tests

You could try searching for yourself using Google. Also, since no one knows what your protocol does it would be difficult to decide what tests would be best to exercise your system.

Solution 1

Found out the following:

System performance you can use oprofile or gprof.
Network profiling you can use ethereal or netstat.
I/O statistics you can use iostat or sar.
For CPU profiling you can use mpstat.

Also for memory leaks dmalloc can be used.
And LTT (Linux Trace Toolkit) provides a graphical event trace of what the
system is doing during a time window.
