"Dim X as New Y" vs. "Set X = New Y"

Slightly speed increase here, The "Set X = New Y" variant is a bit faster than the "Dim X as New Y" direct method. I used the DLL that I made for Early vs. Late binding.

Declarations: Dim ObjTest1 As New VbFibreTest.clsCalc Dim ObjTest2 As VbFibreTest.clsCalc

Start:
    '//Set second object
    Set ObjTest2 = New VbFibreTest.clsCalc

Code:
Public Sub TestOne()
    Dim lngReturn As Long
    lngReturn = ObjTest1.PerformCalculation(100, 50)
End Sub

Public Sub TestTwo()
    Dim lngReturn As Long
    lngReturn = ObjTest2.PerformCalculation(100, 50)
End Sub

New Direct % faster than New Indirect	New Direct (sec)	New Indirect (sec)
11,8%	0,187517	0,167713
24,5%	0,209374	0,168185

When using "As New", the compiler adds a conditional "If obj Is Nothing Then Set obj = New class" before every property and procedure call, yielding a slight performance hit. In most cases, this is negligible, but if you're working with high-performance algorithms, you should declare "As class" and create the object manually.

Thanks for sharing your useful knowledge Tom, I really appreciate it (I'm sure there are others too ;))
