For the database I am currently working on - an ilcd one and not natively available via nexus -  creating product systems takes a lot of time via python ipc

  process_ref = client.get(sch.Process, process_id)

product_ref = client.create_product_system(process_ref, config)

I tried using parallelization - however I could half it - say from 100 seconds to 60 seconds. Would it be possible to efficiently parallelize the create_product_system function  or optimize it. (Even if paid support available)

There are no issues with results / any other things.

Just a comment/question, but you only need to create product systems for the calculation when there are ambiguous linking possibilities in the database and you need to control this via the linking properties (is this the case?). When this is not the case, you can also directly pass the reference process into the calculation setup without the need for creating a product system.

it is a system lci db, hence, I should give this a try. will update here.
