hi,
do you use an OS?
For the memory use and cpu usage you should find yourself the results.  For the 
throughput, you can use some tools that do that, but in many cases you have to 
port that tool to your plateform. As an example netio measures the network 
throughput, but the netio application has to run on both end of the network you 
want to test.
