Trade-off between server load ("send out as many packets as can be 
stuffed into the hardware in one go") and network load ("smooth out
stuff, but have more context switches, interrupts, ... etc. in the 
server").

Now if I had more time :-) it might be worth investigating the (Linux)
streaming server software used, whether it can be changed to invest a bit
more CPU to better smooth out the packets...  OTOH, the kernel might 
just wreck this, and smear it all togehter again.  (*Now* we really get
even more off-topic for c-nsp than usual)
