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
this takes for the same product system (for the entire calculation) 20 GB RAM and is also faster.
