| 00:22 | Removed the direct btree tests - part of the ongoing effort to test by calling only public interfaces. Modify the sqlite3VdbeRecordCompare interface to used a pre-parsed second key - resulting in a 13% performance improvement on speed1p.test. (CVS 4911) check-in: 0e1d84f2 user: drh tags: trunk | |
