Variable declaration Query

[John]

Hi,

I recently came across a .net coding best practises
document which has the following suggestion
"Define frequently used local variables in first four
variables. Since there are direct instructions to load
first four variables, therefore these variables are always
fast compared to remaining variables"

Is it true? any references from Microsoft?

Thanks in advance

That would be interesting, but I have never heard of such a thing.

That sounds like the kind of thing which, even if it's true, should be
avoided for readability reasons except for the *very* few cases where
it makes a noticeable overall performance difference.
