C# or VB.NET - not exaclty the same performance

MS or anyone still claims that C# and VB.NET generate the exact same IL code
?

Hi
Interestingly enough there is a difference in code for vb and C# that
he used for the IO test.
with his code I got:
I/O elapsed time: 46497 ms with a max of 1000000
i: 1000000
readLine:
abcdefghijklmnopqrstuvwxyz1234567890abcefghijklmno pqrstuvwxyz12345678
90abcdefgh

With a few changes to the IO function[1], the result is this:
I/O elapsed time: 9404 ms with a max of 1000000
i: 1000000
readLine:
abcdefghijklmnopqrstuvwxyz1234567890abcefghijklmno pqrstuvwxyz12345678
90abcdefgh

The problem is that he is using old vb6 (And below) functions which
are much slower.
Since the IO test was the main difference between VB.Net and C#, there
doesn't seem to be any difference anymore.

Dim strWriter As New IO.StreamWriter(fileName)
Do While (i < ioMax)
strWriter.WriteLine(myString)
i += 1
Loop
strWriter.Close()
Dim strReader As New IO.StreamReader(fileName)
i = 0
Do While (i < ioMax)
readLine = strReader.ReadLine()
i += 1
Loop
strReader.Close()

plus if a remember my first seminar on .net... at the point where beta 2 was
released... ms only claimed that the msil generated will the equivalent.

if you look at language comformance across different languages... it does
vary...
