Testability improvement. (Closed-Leaf check-in: eed6a331 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: f77f2f48 user: drh tags: btree-opt2)
17:09
Faster loading of cell pointers into the b.apCell array in balance_nonroot. (check-in: fda89b05 user: drh tags: btree-opt2)
16:00
Avoid unnecessary cachedCellSize() calls in the cell partition adjustment phase of balance_nonroot(). (check-in: 6319ee12 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: f7f41818 user: drh tags: btree-opt2)
14:49
Improvements to the way balance_nonroot() constructs the b.apCell array of pointers to cells. (check-in: ee44bb25 user: drh tags: btree-opt2)
13:02
Merge the compound SELECT operator fix from trunk. (check-in: a7be554f user: drh tags: btree-opt2)
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)

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)
