innodb_stats_on_metadata, how does it affects query optimizer?

I have to make some query performance tests on an innodb engine tables.
I read that "innodb_stats_on_metadata" can be set on or off in order to enable or disable statistics gathering by the query optimizer in the innodb engine, is this right? How does this command affects the query performance, does it shut down all statistics or there are other ways to gather the statistics?
