Hello, AFAIK, there's no (performance or size) penalty in enabling it and it provides some very convenient stats directly via sysfs. As a user of the stats, it is very convenient just to have them ready and usable without having to jump through hoops to access them.
I don't understand the reason for not enabling them. Is there any reason *NOT* to enable it? Thanks. Regards, Narayanan.
