Graph Builder is very slow

Dear all,

starting from a few weeks the processing through the Graph Builder seems to be very problematic.
Generally, the processing is much slower comparing with the past months (I’m not working with monster graphs!) and I’ve also noticed some unreliable results. It takes several minutes even to set up the parameters for a simple graph like that (because the access to the tab option of a single function it takes around 20 seconds):


I’m working with the last version (7.0.4). I’ve tried the processing in several computers facing more then less the same problems, for this reason it should not be an issue related to my PC.

Do you think there is a temporary issue with Graph Builder? Someone else is facing similar problems?

Thanks for your help!
