If your network chip/ram/processor combination is not fast enough to run
user space applications and handle a full speed network packet stream
then you either need to send more slowly, make the kernel network driver
more efficient or add some kind of interrupt/polling code to reduce
system load to avoid this. The NAPI layer in the networking code is
designed to make this possible.

Probably worth discussing further on netdev@xxxxxxxxxxx
