IMHO it seems that there is somthing strange going on when while doing the

Their is *always* a "bottleneck" in every test. A bottleneck is absolutely
normal.
In our line of work, it is typically a cpu or or disk bottleneck, depending
on the nature of the program involved.
I think you've discovered that your "cat" test has a cpu bottleneck and the
qmail-inject test has a disk bottleneck. I don't think you can conclude
anything more than that from your test.
Mark.
