| 12:53 | OP_Column optimization: Do not check for an oversize row header unless the row header size is larger than the content available on the local page. check-in: 8125b74cb4 user: drh tags: trunk | |
| 12:39 | Improved header comment on the tool/vdbe_profile.tcl script. No changes to code. check-in: b17ad8fc04 user: drh tags: trunk | |
| 03:34 | Whenever two or more OP_Column opcodes on the same cursor occur in succession, try to reordering them so that the one that extracts the right-most column is first, so that it will warm up the row cache for all those that follow. This gives a small performance boost. Leaf check-in: 08e8f04d12 user: drh tags: reorder-column-opcodes | |
