If i have method code which references this.control for several controls (~30x) should a With..EndWith be used? Does it affect performance in any noticeable way?

Does a fully qualified object (thisform.container1.container2.control) access any faster/slower than this.control in the container2 method?
Should the With be fully qualified? ex: With thisform.container1.container2 vs With This

I know it doesn't affect the functionality (they all work) but i'm curious how performance varies with each technique (and don't know how to test it correctly)

any thoughts?
