Hello,
While migrating to Kodo 4.1 I noticed significant drop in insert performance. I trace it down to some strange batching behavior. While most of the PC were committed with batched inserts one particular class refused to batch and would insert row by row resulting in 10 times performance drop. There is nothing special about the class. Its hierarchy is mapped on base its table except for one of the lowest members which is mapped vertically. Thank you very much Alex Roytman Peace Technology, Inc. 301-206-9696x103
