12:39 | Improved header comment on the tool/vdbe_profile.tcl script. No changes to code. (check-in: b17ad8fc 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.
