I just experienced some commands. Let me explain my little labo ..

As far as I can see, the perf test reached some 5255 requests a second
and the process consumes some 23 Mb.

I ran pmap command continuously while the test and the memory usage did
not increase so ... is that normal, do I have to run another command to
monitor the stack memory usage of one process ????

I hope this can be used as the basic point for a little discussion ..

Many thks for your help ..
