The form designer screen refresh as well as the load of the forms when an user enters in an offer is really slow (minutes to refresh screen).
The server vm machine seams ok when you look at task manager.
A lot of attempts have been made to solve this issue and monitoring the virtual environments where it is installed.
Then asked the database team to verify if everything was ok with the sqlserver machine or with the database itself. 

They discovered that we were using an expired trial license.
That somehow creates serious performance issues. 
After updating the license, all the problems related with catalog forms edition and use were solved.
