Well, you can just time the download. The average download speed is the size of the file divided by the time it took to fetch it. Note that you have to use a large file, large enough that it takes at least 5-10 seconds to download, in order to make sure that the "system" time is small compared to the "network" time.

You could also poll the size of the file in bytes every second and find the difference each time if you want to see it in real-time etc.

Does anyone actually distribute code as .pyc? Usually you have the .py to look at.
Are you trying to look at some code that calculates download speed, or was that an unrelated question?

before 1yr i designed an application for Smartphones, I distributed that app as .pyc
now i want to look that code for reference. My bad-luck i missed the source code, thats why i asked decompiler for .pyc

I've stolen it from PHP, converted it to VB.net.
Google for the PHP version (I don't know anymore where I found it), which should be easier to convert to Python than VB.net.
Imports Microsoft.VisualBasic
Namespace MyWebsite.ClientInfo
Public Class cClientInfo
Public Shared Function GetConnectionSpeed() As Double
Dim iNumKB As Integer = 512
Dim dtTime1 As DateTime
Dim dtTime2 As DateTime
Dim tsDuration As TimeSpan
Dim iLength As Integer = 0
Dim strCheckLen As String = "\n"
Dim strSpeedTest As String = ""
'Response.Flush()
HttpContext.Current.Response.Flush()
dtTime1 = DateTime.Now
iLength = strCheckLen.Length
Dim iIndex As Integer
For iIndex = 0 To iNumKB - 1 Step iIndex + 1
strSpeedTest += "".PadRight(1024 - iLength, "/*\\*"(0)) + "\n"
'Response.Flush()
HttpContext.Current.Response.Flush()
Next
dtTime2 = DateTime.Now
tsDuration = (dtTime2 - dtTime1)
Dim dDeltaT As Double = iNumKB / tsDuration.TotalSeconds
Dim dSpeed As Double = System.Math.Round(dDeltaT, 3)
strSpeedTest = ""
Return dSpeed
End Function
End Class
End Namespace
