this could be one problem, but in my case it's not about becoming big, 
but that some pre-condition checks need to be done (access control, 
etc.) which can take some while
depending on the setup

in the case of the revisions submenus the workflow conditions need to be 
checked for example, and this can contain all kind of checks and hence 
might take some seconds.

You know it's not about minutes, but I think even 5 seconds are too long 
nowadays.

maybe we can workout some proposal. It doesn't mean we have to implement 
it right away, but at least write down our ideas and keep it in mind for 
the beginning.
