  1. What is the minimum and what is the recommended hardware requirement for v14 standalone AND the CLoud version? Can you also add this in a document ? Because these CPU’s that are in the documentation are already old and the working of CPU’s changes as well. What is more important ? To have more cores or just have 2 cores but more Ghz per core?
