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…

I can’t give you any guarantee that it will help, but you could try the “RevitProcess.EmptyWorkingSet” from spring nodes. It will flush any non-critical memory from the active process to the swap file and hopefully spare you from a restart.

Has anyone who have experienced this issue taken a look at task manager after the slowdown begins? The only time I’ve seen such a slow down is when the graph in question has created tons of data, or has touched so many elements in the Revit model, that the ram is completely used up (and then some). …

The biggest reason for slowing down is the way the graph is created. The best way to solve this is to track time taken for each session by adding time.lapse and select 1 or 2 elements. Then try other workarounds to minimize the time where you see the time.lapse is giving you more. Hope it helps!

@Kulkul if composition is the main issue, has anyone compiled anything (custom node, external script) that can perform an audit on a .dyn file? Things like: Number of nodes Number of laces Number of functions upon completion of run Run time Node package dependencies Having this kind of informati…

@Ewan_Opie I mostly use python for my workflows i will add time inside the python so that it helps understand where is the cause :slight_smile: [image]

Hi All, sorry for late reply. First of all, thanks All of you for your discussion here. Very pleased to know that the issue is more often than I thought. I agree with @Greg_McDowell that closing Revit is not the best solution for a not-workshared session. @Kulkul and @Dimitar_Venkov , thanks for th…

Hi @Kulkul , I’m trying to replicate your recommendation for a very simple python node: [image] I have some huge measurement units which I presume they are not seconds. How do you translate it into seconds? Thanks in advance!

Thanks! I also manage to do this: import time tiempo = [] tiempo.append(time.time()) #several times (all needed) tiempo_final = [] for t in range(1, len(tiempo)): tiempo_final.append(round(tiempo[t] - tiempo[t - 1], 4))
