It would be interesting to see if higher burst rates allow you
to use higher rates. Userspace automatically calculates the
bursts based on the timer frequency, which requires that the
timers actually reach that frequency during runtime. With high
packet rates that might not always be the case, so perhaps we
can do better by adding a few percent on top.
