Tools installation
- On your host, install iperf tool (here on Debian/Ubuntu like system):
$ sudo apt-get install iperf
- Install it on your target too:
$ make menuconfig
Package Selection for the target --->
Networking --->
[*] iperf
Test
APF server, Host client
- On your target:
$ iperf -s -i 2
- On your host (192.168.1.10 is the IP of your APF):
$ iperf -c 192.168.1.10 -i 2
Current APF27 results
Linux 2.6.29, direct connection (cross-over cable); asked TCP window size of 16k, got 32k:
-> 82-83 Mbits/sec
Host server, APF client
- On your host:
$ iperf -s -i 2
- On your target (192.168.1.2 is the IP of your Host):
$ iperf -c 192.168.1.2 -i 2
Current APF27 results
Linux 2.6.29, direct connection (cross-over cable); asked TCP window size of 16k, got 32k:
-> 57-58 Mbits/sec
Increase window size
- add -w100k (for example 100kB) to both server and client command.
