The oci_execute & oci_fetch_array calls will take the bulk of the time
because there isn't much else to do for a query. Execution will, of
course, take time while the DB is processing the query. So eliminate
the DB configuration, character set conversion, etc as a cause first.
The OCIAttrGet call are "local" calls and not the relatively expensive
"round-trip" calls to the DB.
Your comment about a lot of columns doesn't match the test you sent me
offline: it only queries two columns.
