    Default Faster Download/Slower Upload

    I'm not sure where the proper place to post this question. I'm running 9.2.0~svn20120216r31181release9.2-1lenny on a dual nic machine. It's pretty simple, one nic to internet, one to local network (single subnet), and also a branch office VPN.

    My problem is my speeds, specifically upload speeds. My connection to the internet is 7x2 business class cable modem. If I connect a laptop directly to the internet and run speedtest.net I see similar speeds to 7x2. See screenshot1 attached.

    If I connect the laptop with a crossover cable to my internal untangle NIC, I see way faster download speeds, but half the upload speed. See screenshot2 attached.

    I use a VOIP phone and the performance has been terrible lately for people on the receiving end.

    I am running the followng plugins:
    Web Filter Lite
    Virus Blocker Lite
    Spyware Blocker
    Spam Blocker Lite
    Phish Blocker
    Application Control Lite
    Firewall
    Intrusion Prevention
    Ad Blocker

    Even if I shut all of these off, my speeds seem way off.

    Any suggestions?

    Thanks,
    James
    What could be causing my upload speed to be so much slower through untangle?

    Check the interface error stats. This is usually the result of duplex mismatch.

    It often helps troubleshooting if you have a good network map. Look here if you want my advice on how to draw one.

    Thanks for the response. Where do I "Check the interface error stats." I poked around in the GUI and didn't see anything.

    Both of my cards are currently listed as full duplex.

    Thanks,

    Use ifconfig in a terminal.

    The output will show errors

    Here's some sample output from my box

    Code:
    eth0      Link encap:Ethernet  HWaddr 00:02:b3:d2:2f:c2
              inet addr:174.x.x.76  Bcast:174.x.x.79  Mask:255.255.255.240
              UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
              RX packets:999819804 errors:0 dropped:0 overruns:0 frame:0
              TX packets:706110046 errors:14 dropped:0 overruns:0 carrier:14
              collisions:0 txqueuelen:1000
              RX bytes:3727275260 (3.4 GiB)  TX bytes:770709548 (735.0 MiB)
    I have 14 transmit errors!

    Of course, 14 whole messed up packets over:

    Code:
    10:20:59 up 239 days, 11:01,  2 users,  load average: 0.07, 0.08, 0.08
    Somehow, I'm not worried about mine. Your results will be a bit different.

    Ok, on my internal NIC there are no errors. On the external NIC I see:

    RX Packets: 711196521 errors: 265 dropped: 624 overruns: 171 frame: 0
    TX Packets has 1 overrun.

    Is that significant considering the number of total packets received? Should I try changing this NIC to half duplex and see if results are different?

    Thanks,
    James

    I would run the command multiple times over a few minutes and see if those numbers are incrementing. If they are, then yes you've got something going wrong there.

    I'm doing a watch ifconfig and the only numbers changing are RX/TX. Maybe I will try a difference NIC and see if things change.

    The NIC I had in there was a DLink DFE-530TX+. I tried a Netgear but my system did not like it for some reason. Next I stuck a Via gigabit card in. I know this is not a high quality card, but untangle at least came back up, and I have no errors.

    Unfortunately my performance is worse, now I'm getting a little over 4 meg by well under 1 meg. Maybe I'll try to get my hands on a more quality intel NIC and see if that changes things for the better.

    Unfortunately still no luck. Now I installed a TPLink Realtek RTL8169SC, which is on the hardware compatibility list. I have no errors on the NIC if I watch ifconfig.

    Now speedtest gives me: 5.24Mbps x 0.90Mbps. I suppose that is closer, but still not even close to the speed outside of untangle as shown on my first post.

    Any ideas?

    Thanks,
    James
