Hi Gertwin, I Did some mistakes on time calculation those are the updated values Test made on w$7 os: No Bulk Operation (with commit and undo enable) Create n: 1 entity in : 0.1890149854s Create n: 10 entity in : 1.0234820464s Create n: 100 entity in : 10.5052122664s BulkOperation (Commit at the end and undo disable) Create n: 1 entity in : 0.193075697126s Create n: 10 entity in : 0.190634392615s Create n: 100 entity in : 0.196410349659s Create n: 1000 entity in : 0.320889925233s Create n: 10000 entity in : 1.33172048646s Create n: 100000 entity in : 11.4102046186s I don't think that we can have best performance ..than this .
