Hi @Grahal

Agree with you, PRT and java consume a lot of Ram but with 16 Go Ram it only use 43 % of RAM

Java consume 2,52 Go ! as you see on my picture

But as previeous said, normaly PRt works on server, so there will be not any influence, or small, with ram

But I don’t understand why it takes only 2 minutes for 60 secondes on the nicola’s computer
