We have the custom batch job that runs slower in the batch mode than not in the batch mode. Also somehow the process (only in batch mode) hangs in different find\exists methods (each run - different method) for a few minutes, and then continues with execution.
From the screenshots you can see that it was 13889 calls of the InventTable::find method, and just one of the call took all the time. Thank you for your help in advance!
