Hi Bugz.
Here's some code so we can test the relative speeds of VB6 and VB.NET. Can you run it on VB6 and VB.NET and let me know the results (as well as CPU speeds of each machine)?

Just for reference, it ran in 13.5 seconds on my computer: VB6, AMD XP1600+.

Feel free to change any of the tests if you want.

Make sure to change the Long/Double datatypes in VB.NET if needed - I seem to remember Microsoft changed Long to Integer or something. Just as long as the test is fair...

VB Code:
  1. Declare Function GetTickCount Lib "kernel32.dll" () As Long

  2. Sub Main()

  3. 'Program to test relative speed of VB6 vs VB.NET

  4. 'Tests mathematical operations

  5. 'Coded 10.8.02

  6.  
  7. Dim x As Long

  8. Dim z As Double

  9. Dim start As Long

  10.  
  11. MsgBox "Press OK to begin mathematical operations. Tests should take <1 minute."

  12.  
  13. start = GetTickCount

  14.  
  15. 'Basic operations, integer & floating point

  16. For x = 0 To 10000000

  17.     z = 17 + 56 / (9 * 263) - 78 / (2.2 * 9)

  18. Next

  19.  
  20. 'Rnd

  21. For x = 0 To 1000000

  22.     z = Rnd

  23. Next

  24.  
  25. 'Trig functions

  26. For x = 0 To 10000000

  27.     z = Sin(23.5687)

  28.     z = Cos(23.5687)

  29.     z = Tan(23.5687)

  30.     z = Atn(23.5687)

  31. Next

  32.  
  33. 'Sqr

  34. For x = 0 To 10000000

  35.     z = Sqr(2315.126)

  36. Next

  37.  
  38. 'Exp & log

  39. For x = 0 To 10000000

  40.     z = Exp(22.561)

  41.     z = Log(22.561)

  42. Next x

  43.  
  44. MsgBox (GetTickCount() - start) / 1000 & " seconds elapsed."

  45. End Sub
