Hello, is the last BPi Vanilla wheezy image somewhere still available for download? I want to run it with Open Media Vault, which still needs wheezy. Thanks a lot. Michael

Thanks for the solution. I have the same problem running armbian wheezy on a banana pi. But I am a complete newbie to linux. Could you explane your workaround in step 2 a bit more precise? Which single steps have to be done? Thanks for your help. Best regards, Michael

Hello, in Armbian TCP buffers are already set. I can change them by putting new values to /etc/sysctl.conf. But, is this elegant? Or would it be better to change directly the values from armbian? In which file configures Armbian the TCP buffers? Thanks a lot and best regards, Michael

Here are the results. Both (server and client) are configured with the same TCP window size. BPi through the above told values (tuning default value) and Win7 PC through TCP window size setting in Jperf. With this I get really stable bandwidth of around 929 MBit/s (BPi => Notebook) and around 643 MBit/s (Notebook => BPi). BPi => GBit Switch => Notebook (Win7 running JPerf) root@bananapi:~# iperf -s -P 0 -i 1 -p 5001 -f m ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 1.00 MByte (default) ------------------------------------------------------------ [ 4] local 192.168.0.18 port 5001 connected with 192.168.0.16 port 53909 [ ID] Interval Transfer Bandwidth [ 4] 0.0- 1.0 sec 92.3 MBytes 774 Mbits/sec [ 4] 1.0- 2.0 sec 113 MBytes 949 Mbits/sec [ 4] 2.0- 3.0 sec 113 MBytes 950 Mbits/sec [ 4] 3.0- 4.0 sec 113 MBytes 949 Mbits/sec [ 4] 4.0- 5.0 sec 113 MBytes 949 Mbits/sec [ 4] 5.0- 6.0 sec 113 MBytes 944 Mbits/sec [ 4] 6.0- 7.0 sec 113 MBytes 946 Mbits/sec [ 4] 7.0- 8.0 sec 113 MBytes 947 Mbits/sec [ 4] 8.0- 9.0 sec 113 MBytes 944 Mbits/sec [ 4] 9.0-10.0 sec 112 MBytes 941 Mbits/sec [ 4] 0.0-10.0 sec 1109 MBytes 929 Mbits/sec Notebook (Win 7 running Jperf) => GBit Switch => BPi root@bananapi:~# iperf -c 192.168.0.16 -P 1 -i 1 -p 5001 -f m -t 10 -T 1 ------------------------------------------------------------ Client connecting to 192.168.0.16, TCP port 5001 TCP window size: 3.00 MByte (default) ------------------------------------------------------------ [ 3] local 192.168.0.18 port 55572 connected with 192.168.0.16 port 5001 [ ID] Interval Transfer Bandwidth [ 3] 0.0- 1.0 sec 62.4 MBytes 523 Mbits/sec [ 3] 1.0- 2.0 sec 76.4 MBytes 641 Mbits/sec [ 3] 2.0- 3.0 sec 79.0 MBytes 663 Mbits/sec [ 3] 3.0- 4.0 sec 78.9 MBytes 662 Mbits/sec [ 3] 4.0- 5.0 sec 78.6 MBytes 660 Mbits/sec [ 3] 5.0- 6.0 sec 79.1 MBytes 664 Mbits/sec [ 3] 6.0- 7.0 sec 78.6 MBytes 660 Mbits/sec [ 3] 7.0- 8.0 sec 76.0 MBytes 638 Mbits/sec [ 3] 8.0- 9.0 sec 78.8 MBytes 661 Mbits/sec [ 3] 9.0-10.0 sec 78.4 MBytes 657 Mbits/sec [ 3] 0.0-10.0 sec 766 MBytes 643 Mbits/sec

Sometimes it is usefull to write problems down to find the right solution. The answer to my question seems to be easy. Just increase the default value of net.ipv4.tcp_rmem = 8192 873800 8738000 #(min default max) net.ipv4.tcp_wmem = 4096 655360 6553600 #(min default max) will change the TCP window size. Measurements will follow.

Hello, I am setting up a filserver, using a BPi and a WD Red 3TB connected to the sata port of the BPi. The BPi runs armbian v4.5 with vanilla kernel. For the first tuning I used the recommandations from tkaiser (thanks a lot for that).

Hi PaceyIV, thank you for your reply. So yout get 4x the write and 5x the reading speed of my measurement. I think there must be something wrong in my system. Does anyone has an idea what the problem could be? Thanks a lot and best regards, Michael

I was connect via putty to the banana pi and started iozone through putty (connection 1Gig Ethernet). But this should not matter, because the iozone test runs internally on the banana pi, no transfer to the connected system.

Hm, I do not understand your question because I think the answer is written in my question: - Armbian 4.2.2 wheezy - BananaPi - iozone -a -y 512k -q 1024K -s 2000m -g 2000m -i 0 -i1 - WD Red 3TB, connected to SATA on BananaPi - HDD format is EXT4 Which information do you miss? Thanks a lot.

I found the answer for my question: http://www.lemaker.org/thread-15543-1-1.html Thanks a lot.

Hi Igor, hi all, I use a BPi M1 and today I tested Igor's debian wheezy 4.1.2 image. It works really great. Thanks a lot. As mentioned in the FAQ I had a look at /etc/init.d/cpufrequtils. As written there it is possible to change the frequencies. The possible values are stored in "scaling_available_frequencies". The default value for "max_speed" in Igor's image is "max_speed=1010000". But this value ist not available inside "scaling_available_frequencies". "cpufreq-info -m" tells the current policy: frequency shoukd be within 480-960 MHz. 960 MHz is the maximum value in "scaling_available_frequencies". Normally BPi is able to run at 1008 MHz. How can I change the values inside "scaling_available_frequencies"? Is there a reason why the govenor "interactive" ist choosen? Thanks a lot. Best regards, Michael
