Hi
I decide to test RRI-B as simple router (without NAT): [Host A] ---
[RPI-B] --- [Host B]
I've created two vlans on RPI (if_vlan.ko was load as module) and run
iperf between Host A and Host B:
[Host A~]# iperf -c 192.168.0.249 -P 5 -i 5 -t 300 | grep SUM
[SUM] 0.0- 5.0 sec 4.62 MBytes 7.76 Mbits/sec
[SUM] 5.0-10.0 sec 4.75 MBytes 7.97 Mbits/sec
[SUM] 10.0-15.0 sec 4.25 MBytes 7.13 Mbits/sec
So RPI-B network's throughput was around 20Mbit/sec of full-duplex traffic:
root@raspberry-pi:~ # netstat -hw 1
input (Total) output
packets errs idrops bytes packets errs bytes colls
2.8k 0 0 2.3M 2.8k 0 2.3M 0
2.3k 0 0 1.9M 2.3k 0 1.9M 0
2.1k 0 0 1.7M 2.1k 0 1.7M 0
2.3k 0 0 1.9M 2.3k 0 1.9M 0
2.7k 0 0 2.2M 2.7k 0 2.2M 0
Is this maximum for RPI-B by it's hardware limitation or it possible to
tune something?
P.S. some info about my setup of RPI-B:
gpu_mem=8Mb
FreeBSD 10.0-CURRENT r248554
Kernel's config (original RPI-B) was modified by commented out
#makeoptions MODULES_OVERRIDE=""
and added
options LIBALIAS
options IPFIREWALL
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=100
options IPFIREWALL_DEFAULT_TO_ACCEPT
options IPFIREWALL_NAT
options IPDIVERT
options IPSTEALTH
options DUMMYNET
options ROUTETABLES=2
Ipfw has one rule - allow ip from any to any
Top shows during the test:

Thanks.
