Hi All, I am working with an APU2 board (4gb, 3 lan and AMD CPu 1Ghz you can see specifications here http://www.pcengines.ch/apu2.htm) to make a router/firewall.
Before choosing the OS I want to use I have done some benchmarks. My first benchmark is: 1) Copy of a big file (17GB) compressed with gzip from a Windows 10 machine to a Windows 8.1 machine. This is done by using CIFS on Windows. Each machine is at one side of the router. The results are strange: With OpenBSD and Linux (alpine linux 3.4) I get the maximum speed (112Mbytes/sec) while with NetBSD the speed is limited to 70Mbytes/sec. All the hardware is identical and all the router OS are installed on the APU2. To do the tests, I simply reboot the router and I choose an other OS. Do you have an idea why there is a such big difference? Should I tune some specific network parameters on NetBSD? I have done a second benchmark by transferring the same file with ftp, but this time the second machine was a Linux server (running on the same hardware as the Windows used for the CIFS transfer) and I get similar differences (80-85Mbytes with Linux Router,50-55Mbytes with NetBSD). The benchmarks were run without any firewall. Thank your for your help, best regards, Alan
