9 check-ins tagged with "btree-opt2"
|21:35||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|
|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|
