It seems like your computer is running out of memory when you run the longer process (which apparently is memory-heavy). Windows starts swapping and that slows down all running applications, including EasyMorph.
When you just load one CSV and export it, it doesn’t cause Windows run out of memory and start swapping. Therefore, it’s fast to execute.
I would suggest running memory-heavy processes in Launcher as it’s more memory-efficient than Desktop. Desktop keeps all intermediate results in memory (albeit compressed) because they are needed for instant data visualization. Launcher (as well as Server) doesn’t do data visualization and keeps in memory only some intermediate results.
- Close all other applications when running memory-heavy projects in EasyMorph to have more RAM available.
- Use Windows Task Manager or a 3rd party RAM indicator to watch memory consumption
- Run memory-heavy projects on Server
