Shaper wizard: it set higher speed than specified?

  • pfSense 2.0.2 Release, using "Single Lan multi Wan" wizard.

    I set the upload and download speed to  "23"  "Megabit" in the wizard.

    However, when I look at the queues, this is not what it is actually using:

    LAN, Bandwidth  [Blank    ] [Kbit/sec]

    • qInternet
      • Bandwidth [24117.248]  [kbit/sec]
      • Service Curve, Upper limit, m2  [24117.248Kb]
      • Service Curve, Link share, m2  [24117.248Kb]

    I have no idea where it is getting that number from. It doesn't even work out using binary (1024) math:

    24117.248Kb / 1024 = 23.552 Mb

    I don't know what the point would be of setting the shaper to think we have more bandwidth than we actually do.

    Though I am going to contact our ISP to get our exact bandwidth in bits/sec so I'm not dealing with 1000/1024 conversion issues.

  • Ah, I see it is

    24117248 / 1024 / 1024 = 23

  • Boy that is weird. The ISP says we are 23 * 1000 * 1000 or 23,000,000.

    So apparently I gotta convert from 1000 to 1024 for the shaper wizard?

    23,000,000 / 1024 = 22460.9375

    I paste that in:

    And the resulting config is different.

    What's going on here?
