e4d9081307 Change BtreeMoveto so that it can be biased to the right or to the center. 
Use a right bias when appending and a center bias when searching.  This
gives about a 15% reduction in calls to sqlite3VdbeRecordCompare. (CVS 3741)

f1d68b3096 Bias the b-tree binary search toward the high end. The common case is to

are fewer comparisons. (CVS 3740)
