For the exiobase database, you need quite a lot of memory (RAM) when building a product system (about 40 GB) and even more for calculating; note that this untruncated version of exiobase is not available in other LCA software.
Here the statistics of one product system: almost 30 million connections, processes with more than 5000 input products:

You should calculate the database via the direct calculation, bypassing the product system
![](https://ask.openlca.org/?qa=blob&qa_blobid=5808476473493130213)
this takes for the same product system (for the entire calculation) 20 GB RAM and is also faster.
Best wishes,
