Alix boards throughput

  • What would be the achieved throughput when using an alix (500mhz/256MB) board as a firewall (100Mbit WAN <-> 100Mbit LAN) ?

  • I haven't tried yet, but others have reported 100 Mb wire speed.

  • Just finished some testing and here are my results with netio:

    TCP connection established.
    Packet size  1k bytes:  10370 KByte/s Tx,  10822 KByte/s Rx.
    Packet size  2k bytes:  10396 KByte/s Tx,  10921 KByte/s Rx.
    Packet size  4k bytes:  10574 KByte/s Tx,  10927 KByte/s Rx.
    Packet size  8k bytes:  10567 KByte/s Tx,  11026 KByte/s Rx.
    Packet size 16k bytes:  10596 KByte/s Tx,  11029 KByte/s Rx.
    Packet size 32k bytes:  10613 KByte/s Tx,  11066 KByte/s Rx.

    So basically, it is going at close to 100 mbit wirespeed…. Amazing!

    For those interested, the specs for the host and client used for the netio testing were:

    host: Athlon 850 MHz with intel nic
    client: Pentium 4 - 1.8 GHz with intel nic

  • My connection (100/10MBit/s) normally peaks at 80MBit/s downstream while simultaneously hitting the ceiling of 10Mbit/s upstream with appr. 2000 active states on an Alix2C3 running embedded 1.2-RC3. The numbers were more or less the same when running m0n0wall 1.3b5.

  • Is there any chance you have the ALIX board running as an OpenVPN client and can test the throughput of that as well?

  • @naughtyusmaximus: No, sorry. I'm currently not using it as a VPN client/terminator of any kind. I might in the future though, in case of which I'll post the info.

  • Ok thank you

    I've just ordered one which will be used as an OpenVPN client - if I get it set up before you I'll post my results ;)

  • I have OpenVPN running on mine to connect road worriers
    havn't done any troughput tests, but from just using it, it is way faster than ipsec or pptp

    I'm on a Alix 2c2

    i wonder how you managed to get such good speed.

    i'm using my pfsense (1.2-rc4) at a vdsl line (50/10mbit) and can't get more than ~2MB/s downstream… as soon as i remove the pfsense i get 4,7MB/s

    my setup is the following:
    vdsl-modem -> isp-router -> 1st lan -> pfsense -> 2nd lan

    any hints how i could improve my speed?
