Number of actions per controller


I’m coding the administration part of an application to deal with all
administrative tasks the (authorized) user can perform in it.I found
that as
all the actions are logically related, it’s ok to have them all in the
“admin” controller, but I end up with more than 35 actions. I’m
wondering if
I should split the actions in more focused logical units and distribute
along 4 or 5 different controllers.

I would end with something like
instead of having just
which is not a big issue.

My question is, apart from clarity, there is some good reason to put a
on the number of actions a controller must have??
Any performance deal with some of the two ways?
What is your number of actions per controller ratio for medium size
applications (no just basic CRUD apps)?
