Downloads are slower through pfsense than directly to modem.



  • Hello I am running stock pfsense on a pentium4 ht 3.4 ghz computer with 2gb ddr2 ram and the download speeds are significantly slower than when connected directly to the modem I have Comcast 25mbs on a Motorola sb6141 modem. What would be causing this?

    How significantly? What NICs are you using?
    Check the Status: Interfaces: page for errors on the interfaces. A significant slow down can be the result of a speed/duplex mismatch which would cause a lot of errors.

  • speed an duplex are the same and the nic is a cheap realtek gigabit nic. But my connection is only 25mbs

    Yes that machine should have no trouble at all with 25Mbps whatever NICs you're using as long as they're configured correctly.
    So no errors then?
    What sort of speed reduction are you seeing?
    Are you using traffic shaping or running any packages?

    I am on the 25mbps plan with comcast, and my pfsense is just 1 of a few VMs on a N40L with Turion II Neo 1.5ghz Dual-Core, pfsense vm has only been given 512 and I max out both my download and upload pipe.  So I would have to think such a machine should be able to handle it no problem.  As asked what speeds are you seeing, and have you validated these speeds from more than just 1 test location?  And what speeds are you seeing?
