vbnet String versus StringBuilder

Using System.Text

Sub Main()
	Dim sDate, eDate, sTime, sbTime As Long
	Dim LoopCount As Long = 10000
	Dim s As String = ""
	Dim sb As New StringBuilder

	sDate = Now.Ticks
	For i = 0 To LoopCount
		s = s & Guid.NewGuid.ToString
	Next
	eDate = Now.Ticks
	sTime = (eDate - sDate)
	'Console.WriteLine(s)
	Console.WriteLine("String Concatenation: " & sTime.ToString)

	sDate = Now.Ticks
	For i = 0 To LoopCount
		sb.Append(Guid.NewGuid.ToString)
	Next
	eDate = Now.Ticks
	sbTime = (eDate - sDate)
	'Console.WriteLine(sb.ToString)
	Console.WriteLine("StringBuilder: " & sbTime.ToString)

	Stop
End Sub
Highlights the performance advantage of using StringBuilder.
