how deep can a package be? any performance issue?

Hi experts,

Is there any performance issue if I create deep path to a class for the sake of a well organized classes?

com.mycompany.mydivision.projectA.forms.news.headlines;

com.mycompany.mydivision.projectA.forms.news.events;

com.mycompany.mydivision.projectA.dao.calendar.events;

or

a.b.c.d.e.f.g.h.i.j.k.l;?

any reading materials on this?

Thanks
