HI ,

I am trying to do some performance measurements on  lwip in Genode and RPI,

I setup Genode on RPI and then run netperf_lwip

from my client PC  with   Linux 12.04 as OS , Intel Core I7
I got

#netperf-2.6.0 -H 192.168.12.211 -P 1 -v 2 -t TCP_STREAM -c -C -- -m 1024

the Throughput values is looking strange!

when i run then netperf_lwip on genode based on linux platform i got totally different results

#netperf-2.6.0 -H 192.168.12.211 -P 1 -v 2 -t TCP_STREAM -c -C -- -m 1024
