The article is useless. The author's diagnosis of the problem is way off.
There's no COM interop involved. And the test is done on .NET 1.1. The
performance difference has disappeared in 2.0.
Did you check out the link in one commenter rebuttal? I tend to
disbelieve that the = is slower because I believe that the testing
methodology was wrong.
For the record, my testing confirms that under fw 1.1, the (almost) 2 to 1
performance loss of '=' vs .equals is true. I'm glad to hear that the
problem is gone in 2.0.
I'm trying to check whether a string is all digits. This part is

for( var idx=0; idx < foo.length; idx++ ) {...
