Well, if oracle stores all the meta data in UPPERCASE, then for a query in
which object names are written in lowercase characters will force the parser
to convert it into UPPERCASE for comparison, in which case there should be a
negligible difference if the name of the objects referenced by the query is
written in UPPERCASE.
But that should be so negligible, that it can be safely and wisely ignored

No, there will not be any noticable difference in performance.
