If you don't show your execution plan or other statistics
is very difficult to get an idea of your problem.
Basically upper(sepr) should be indexed as a function index or hopkinsepr
as an index.
I think without indexes upper(sepr) implies a small overhead because it
have to upper a string, and without indexes both will have to do a full
scan.
If you don't know how to get an execution plan
my paper could help you
