I've had a recent os replacement win7 x64 (harddrive died and i got another and started from scratch). There is 1 volatile function. The problem is - it didn't slow me down with the old installation.
At first i thought I've overburdened it with more stuff to do, but then it seemed suspicious and i finally rolled back to a much older version of my document to only find the delay applies there as well - except i never had it before.
If i copy text from outside of excel and paste it into a cell, it may take half a second to figure it out. (which is ok). If i type the volatile formula it takes the same time and figures it out. (which is ok).
The problem comes when I copy a cell that contains the same text or formula and paste it onto the next cell - the software practically clogs for over a minute with its "Calculating: (6 Processors): xx%"... Which is weird as CPU never goes above 20% load with 2 browsers and photoshop in the background. Also with manual calculation it works in under 1 second when it triggers a recalc upon save file.
Is it the chip-set drivers, or some excel option i need to tweak i don't know, but there is definitely something going on thats making a mess. Any ideas?
It takes me more than five seconds to copy any cell to any other cell in the sample file. It used to take me half a second to do this in a 2mb document.

And module code:
Function ReqOffset(ReqAdd As String, iOff As Integer) As String
Application.Volatile True
Dim V As Variant
Dim i As Integer
V = Split(ReqAdd, " ")
For i = LBound(V) To UBound(V) Step 2
ReqOffset = Trim(ReqOffset) & " " & Range(V(i)).Cells(CInt(V(i + 1))).Offset(0, iOff).Value
Next i
End Function
