Use unsigned indexes in MySQL?

Is there any win/loss of performance when using the UNSIGNED attribute in the primary keys?
Anyway, are there any good UNSIGNED indices, in addition to increasing the range of numbers?

So simply "No" without any arguments?
As I recall, unsigned int improves the performance indexes, and mysqlperformanceblog.com there was an article about this (can't find now exactly, but here
www.mysqlperformanceblog.com/2008/12/22/high-performance-click-analysis-with-mysql/
for example here is on looking for unsigned). You can still read their book High Performance Mysql, preferably 2 part.
