| 16:56 | Optimization: Try to avoid unnecessary btree searching when repositioning a cursor to the next row. (check-in: ee793d30 user: drh tags: trunk) | |

| 21:47 | A better implementation of the moveto-neighbor optimization that checks for nearby rows on adjacent pages. (Closed-Leaf check-in: 2c4ecb85 user: drh tags: btree-moveto-neighbor) | |
| 16:54 | B-tree optimization: When seeking on a rowid table that has already been positioned, check to see if the new row happens to be the next row on the same leaf page. That is a reasonably common case, and if it is true it avoids a full binary search. (check-in: 8e5cfb20 user: drh tags: btree-moveto-neighbor) | |
| 16:27 | Change sqlite3_blob_reopen() to call sqlite3VdbeExec() directly rather than going through sqlite3_step(). Performance enhancement. (check-in: 347df3c1 user: drh tags: trunk) | |
| 15:55 | In the kvtest.c test utility, reuse the buffer into which blobs are read, rather than reallocating it for each row. This is a closer match to how other test programs work, and thus provides a better comparison. (check-in: 0d1ad13a user: drh tags: trunk) | |
