Genode network performance

On the subject of improving network stack performance, I observe 50%
less throughput on Genode+Fiasco.OC+LWIP versus Linux on exactly the
same Intel-based hardware. I am sending UDP packets; Linux @ 324K PPS
and Genode @ 167 KPPS. Using 64bit kernels. This is using
out-of-the-box Genode IPXE DDE with E1000 NIC card.
Does this performance difference sound reasonable and expected? Is there
some expected significant performance overhead with using DDE as opposed
to a native NIC driver?
My next step will be to look at raw ethernet packet performance.
