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 MIGRATED TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.12.211 () port 0 AF_INET Recv Send Send Utilization Service Demand Socket Socket Message Elapsed Send Recv Send Recv Size Size Size Time Throughput local remote local remote bytes bytes bytes secs. 10^6bits/s % S % U us/KB us/KB

the Throughput values is looking strange!
when i run then netperf_lwip on genode based on linux platform i got totally different results
