So definitely end of argument. ODO is a cpu hog.

No, not at all! The performance cost of ODO depends
on how it is used, not ODO itself.

ODOSLIDE is particular to implementations and is
non-standard. Comparing the value of an index-name
to a numeric value may be expensive; but comparing
the values of two index-names is not. Don't do these
two things and using ODO is only a few percent
slower than using fixed tables, for the operations
tested. For other operations, it may be faster.
