00:05 | Performance optimization on balance_nonroot() and related routines. 2.6% faster overall with a size increase of less than 750 bytes. (check-in: 25131e7062 user: drh tags: trunk) | |

21:35 | Testability improvement. (Closed-Leaf check-in: eed6a33145 user: drh tags: btree-opt2) | |
18:24 | Multiple overflow cells are always adjacent and sequential. Exploit this invariant for a small size reduction and performance increase and add assert()s to prove the invariant. (check-in: f77f2f48f4 user: drh tags: btree-opt2) | |
17:09 | Faster loading of cell pointers into the b.apCell array in balance_nonroot. (check-in: fda89b0512 user: drh tags: btree-opt2) | |
16:00 | Avoid unnecessary cachedCellSize() calls in the cell partition adjustment phase of balance_nonroot(). (check-in: 6319ee1256 user: drh tags: btree-opt2) | |
15:36 | Change pageInsertArray() and pageFreeArray() so that they use the CellArray object and compute cell sizes as needed, resulting in smaller and faster code. (check-in: f7f4181811 user: drh tags: btree-opt2) | |
14:49 | Improvements to the way balance_nonroot() constructs the b.apCell array of pointers to cells. (check-in: ee44bb25b2 user: drh tags: btree-opt2) | |
13:02 | Merge the compound SELECT operator fix from trunk. (check-in: a7be554f4b user: drh tags: btree-opt2) | |
12:19 | Test that the left and right sides of a compound SELECT operator have the same number of expressions in the expanded expression list before beginning to generate code. (check-in: 4df852ce26 user: dan tags: trunk) | |
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: 43844537e8 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: 1687287151 user: drh tags: btree-opt2) | |

14:11 | Update the fuzztest data using the latest test vectors discovered by AFL. (check-in: b97f9cf73e user: drh tags: trunk) | |
