| 01:13 | Performance optimization in accessPayload(). (check-in: ebb1fd98 user: drh tags: trunk) | |
| 00:31 | Simplify the accessPayload() routine so that it always populates the overflow page cache. In the one case where populating the page cache can lead to problems, simply invalidate the cache as soon as accessPayload() returns. This simplification reduces code size and helps accessPayload() to run a little faster. This backs out the eOp==2 mode of accessPayload() added by check-in [da59198505].

| 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) | |

| 21:20 | If compiled with SQLITE_INLINE_MEMCPY, all memcpy() calls are replaced with in-line code. With that change, cachegrind shows which memcpy() calls are taking the most time. This is a performance-measurement hack only and is not for production use. (check-in: 9ed38521 user: drh tags: trunk) | |

| 13:06 | Additional ".selecttrace" debugging output when the query is transformed from a DISTINCT into a GROUP BY. (check-in: 5a469145 user: drh tags: trunk) | |
