lexicals are always faster than globals - provided you have direct access to them - since package globals require a hashtable lookup
package variables do not require a hash table lookup; each relevant op contains a pointer to the typeglob (or in the case of ithread builds, an index into the pad which contains the typeglob). It's still slightly slower than lexicals since a few more pointers have to be followed.
