Measuring the performance of a C program on a Raspberry Pi

My C (PolarSSL Simple Client) runs on Raspberry Pi. I want to measure the RAM usage and cpu timings of this client. Valgrind does not work on Raspberry Pi. Instead, it throws the following exception:

==3199== valgrind: Unrecognised instruction at address 0x4843588.
==3199==    at 0x4843588: ??? (in /usr/lib/arm-linux-gnueabihf/libcofi_rpi.so)

From what I'm collecting, this exception is the well known Walgrind problem on Malin.

What can I do to fix this problem?

In terms of performance, oprofile

might help you. It requires some work (kernel modules) to work.
