My b2evolution Version: 1.10.x

Hi folks, I was scoping the docs page for info on sub-dir and even though it referred to "Phoenix" release it seemed relevent. It referred to using several sub-folders. My first question is what is the sensible limit? 10? 20? 30?

And at some point do more sub-dir inhibit performance? Or is performance determined by the hosts capabilities?

Yep, Newbie Q's I know but I would like an answer!
