You don't need to test this as this is commonly know already. You will
get bad performance.

I cannot say that it doesn't cost time, because obviously it does cost
some cpu cycles, but this won't be noticeable at all. Creating the
idea is like 1 billionth of the time it takes to actually create the
folders. I don't think the random folder structure is a bad idea. You
can also create the user 123 below


Furthermore, I don't think you should store the jcr path back into the
database of the created user! You can much better store the identifier
of the created user node.
