| 02:37 | Avoid computing cell sizes in balance_nonroot() until they are really needed. This gives an overall 1.7% performance gain for about 1000 extra bytes of code space. (check-in: 43844537 user: drh tags: btree-opt2) | |

| 20:02 | Change the way that balance_nonroot() partitions cells between the sibling pages such that a scan of the cell size array is not required. (check-in: 16872871 user: drh tags: btree-opt2) | |

| 18:13 | Split out all four cases of cellSizePtr() into different methods, each optimized for the specific page type. This gives a 0.36% performance increase at a cost of about 300 bytes of code. (Leaf check-in: 522502ec user: drh tags: btree-opt) | |
| 14:11 | Update the fuzztest data using the latest test vectors discovered by AFL. (check-in: b97f9cf7 user: drh tags: trunk) | |
| 13:18 | Make sure that the likelihood() function does not mess up generation of result-set code when it is used (inappropropriately) in a result-set expression. (check-in: 7cdbae62 user: drh tags: trunk) | |

| 20:31 | Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: 172a864d user: drh tags: trunk) | |
| 20:08 | Fix corner cases involving corrupt varint values in record headers. (Closed-Leaf check-in: 3189116b user: drh tags: btree-opt) | |
| 18:24 | Performance improvements in btreeParseCell() by inlining the varint decoder. (check-in: faab0ed9 user: drh tags: btree-opt) | |
| 17:19 | Add the MemPage.xParseCell method and provide various implementations (variations on the former btreeParseCellPtr()) depending on the page type. (check-in: 41d03d88 user: drh tags: trunk) | |
| 15:07 | Make cellSizePtr() a method on the MemPage object, with alternative implementations depending on the page type. This results is a small performance improvement and size reduction. (check-in: 02f7e9d7 user: drh tags: trunk) | |

| 15:26 | Further #ifdef changes in speedtest1.c in order to support SQLite back to version 3.3.9 and perhaps even earlier. (check-in: 9246eca5 user: drh tags: trunk) | |
| 14:32 | Pervent the likelihood() function from moving ON clause terms of a LEFT JOIN into the WHERE clause. Fix for ticket [5f60b11fc8e23490e2] (check-in: ed96e14a user: drh tags: trunk) | |
