performance Issue

We have an application, which imports reports and movements from external system and process on it.In this process we are adding reports to the existing one and if the report is new then creates a new line in mendix. Also we are linking movements to the existing reports. This process is taking aorund 3 and half hours to complete. we are looking for some performance improvement, could you guys suggest something over it.

Abhinay, without seeing your app, it's hard to say what is slowing you down. Breaking your processing into batches may help

A few suggested readings/viewings:

Finally, Mendix offers performance review services if you are still stuck.
