Nothing against beforefter. It's a very useful tool, especially given Linux's lack of a method to clear interface counters. But it still is very cumbersome to use in the scenario I mentioned, having to save the stats before and after a test on each of several systems, and then having to run beforeafter on each of those systems. Then you need to do this all again for every test run. It's just not very efficient.
I don't know why the major objection to adding a small amount of code to the kernel that would make life a lot easier for hundreds (or more) of Linux network adminstrators. And the snapshot/diff idea would not be complex to maintain and would also address the issue of some hardware not having a clear hw stats capability.
