    Hi,

    what makes insert faster when doing it every 100 objects? In each case the
    same number of inserts will be generated.

    Can, beside using templates, Cayenne be configured to do something like:

    INSERT INTO *tbl_name* (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

    That is one insert for 3 rows, which is more efficient (mysql).
