Hi All, I know that this topic has been discussed before, but I haven’t found a solution to the problem and I think it is a really important topic. I’m experiencing the same problem described here: [image] Dynamo Makes for a Slow 2016? Revit Might have something to do wi…

@Greg_McDowell I think that those numbers are indicative of read/write speeds not the amount of data being stored there. Out of curiosity after clearing the cache does the undo history go away? I can elaborate on workshare monitor more in a PM but even stuff as simple as when a user syncs and how l…

@jacob.small On WSM I’m interested, PM me too please. I’ve seen other issues (Revit-related/Relational database related) with workshared models, logical but concerning if not noticed, and lets share it after investigating. Marcel

Thinking about how Dynamo is maintaining the Undo history might explain some of the issues I’m/we’re having with large graphs affecting lots of elements. Perhaps the core program could introduce an option to dump the information from memory rather thank keep it. Thoughts?

If you are using python within your script, have you looked at the revit api’s “dispose” calls to remove elements from memory after you have done what you require?

Hi @Brendan_Cassidy , can you work a litte bit ioon this? Which methods are you talking about?

Hi @Greg_McDowell and @jacob.small . I agree with @jacob.small on the fact that is a RAM issue. I tested 2 computers: one with 8 Gb RAM and another with 16 Gb. On both the usage of RAM memory after the process rises to the 80%-85% so the guess is that all the processes remain stored in there after f…

I know it isn’t really a solution but if you disable your view extensions on dynamo, it stops crashing.
