Therefore, only the code executed within 'tcpsvd' should be measured. It is obviously that a slow program would increase absolute numbers and reduce the relative ones. Dynamic linking against glibc would make small programs significantly slower so I used the fastest possible 'r'. Ok, telling the 'resD.glibc.*' results at this place was wrong and related to other statements in this thread.
