Make the implementation of the sqlite3_aggregate_context() interface faster for second an subsequent invocations. This helps all aggregate functions to perform better. check-in: 802148f3 user: drh tags: trunk
17:41
Improved performance in the type handling of arithmetic operators in the VDBE. check-in: 0c0a6039 user: drh tags: trunk
17:21
Performance optimization in the applyAffinity() logic inside the VDBE. check-in: 25f2246b user: drh tags: trunk

Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine into two with the second routine named sqlite3BtreeCursorRestore(). The first now only reports whether or not the cursor has moved and the second tries to restore the cursor. This allows the sqlite3VdbeCursorMoveto() routine to be refactored to avoid stack pointer movements, for a noticable performance gain. check-in: ce123b5c user: drh tags: trunk
22:26
Factor the saveAllCursors() routine of btree.c into two separate routines, for a noticable performance improvement. check-in: 3eb08439 user: drh tags: trunk
21:58
Performance enhancements in the b-tree mutex logic. check-in: 89145306 user: drh tags: trunk
20:35
Combine the pcacheAddToDirtyList() and pcacheRemoveFromDirtyList() routines into a single pcacheManageDirtyList() routine. The resulting binary code is slightly faster and a few bytes smaller. check-in: 6bcf1af6 user: drh tags: trunk
18:48
Performance enhancement in sqlite3PutVarint(). check-in: a929be55 user: drh tags: trunk
18:00
Split the sqlite3Error() routine into sqlite3Error() and sqlite3ErrorWithMsg(), for a slight size reduction and performance increase. check-in: cf561d1f user: drh tags: trunk
