Calculations taking long (openLCA 2.2)

Question

Hello,

I am trying to compare 5 product systems. Each product system is just one process. The calculations take ~2min per product system. Is this normal? Is there a way to speed up?

I have allocated 30GB out of 32GB RAM towards openLCA. I am running openLCA 2.2 from .exe in unzipped folder located on my local drive. Initially, I did TRACI methodology and then AWARE. No significant difference. See attached screenshot of log file (blue highlighted are for run using TRACI and the bottom 5 are for AWARE).

Thanks,

Hi, the time needed does not really depend on the LCIA method but on the size of your product system which in term is influenced by the database you are using. Could you explain please? Thank you, Andreas
