- an engine with a lot of historic (activity/process) instances that have the same end time (called tx here). Let's assume there are 20 instances with tx in total.
- Optimize starts the import
- the imports one page which contains only the first 10 instances of tx.
- Optimize will skip the remaining 10 instances during the import
- all histoirc instances are imported independent of how many have the same end time.
