A360 Collaboration for Revit Slow

After Autodesk's "A360 Collaboration for Revit Team" updated C4R, our models have become painfully slow. When we open a project from A360 C4R and waited a sufflient time for the cache to download, changing views take about 20-45 mins (generating graphics...). We've updated all software via the download manager. Hardware specs are 2x-3x better than what Autodesk recommends. Tried Different computers with a newly downloaded cache for the same project same issue. Prior to update, the models performed just fine. Any insight would be appreciated!

I was just coming to post something similar to the forums and found this post. 

The last 3 days (July 20-22) our whole team has been waiting for revit to complete the simplest tasks. I am working on area plans and every other area boundary line I draw takes anywhere from 5 seconds to 5 minutes. My views seem to open fine and in a timely manner. This is not just my computer, I have confirmed it with my team of 9. In addition about every 5-10 commands prompts the accessing model window.

Revit build 20150512_1015 update release 8. My computer has an I-7 CPU, 32 gb ram, 1 gb quadro GC so it is not the computer. Our firm has a fiber optics connection and 20 gb of bandwidth. Last week everything was working fine. 

 

I was unaware of an update to A360 so maybe that is it.

We are seeing degraded element borrowing performance at the moment.  Can you guys please post Revit journals from your Revit sessions when you experience these performance issues?  We need to correlate your expereince with other reports.

Kyle,

 

Thank you for the quick and timely reply and for providing the link to the health dashboard. I have located the Revit Journals you asked for. Where would you like me to send them and do they contain project information? 

 

Thank you,

 

Steven

This has come in from a user on this particular project... We are experiencing long load times while working with the model; these mainly consist of long initial load times (about 20 minutes) and long view load times (10 minutes minimum). We’ve noticed that the length of the view load times are in direct relation to the amount of plan regions that exist on the view. In some view cases, where as many as 20 plan regions are placed, we experience times as great as 30 minutes on our fastest machines.

 

We believe this problem to be a combination of the way Revit 2016 loads and caches views and initial problems in the Architect’s Revit model. Apart from the extreme size of the file we have discovered what we believe to be a key to the problem. There is a family that is placed in multiple places throughout the 7 Multi Family Residences that has unbounded elements that span at least 23000’ which when we initiate a “zoom” command results in a 46000’ plan range.

There is a 20 mile limit for geometric accuracy (if all of the elements within the model don’t fit within a box 20 miles on a side), then you can see strange behavior, and issues with measurements/placement of elements.

 

However, 46,000’ is a little less than 9 miles (not 20).

 

I suspect the reduced performance currently occurring with the Collaboration for Revit service is related to (if only compounding) the issue you found with the family.

 

If you save out a separate copy of the model, remove the family and save (with a new name) to C4R is the performance issue gone (this could show if the issue was specific to the family alone)?

Steven,

Journals contain model file names, but that's about it in terms of project info.  The rest is a bunch of verbose logging of internal operations.  If that concerns you, feel free to send a private message to me that contains the Journals.

It does seem like we are having a problem with a unit family and multiple plan regions in a view. We're testing now

The Journals are too large to attache to this post and I do not see an attachment area in the private message. I would like to send you three Journal files. (they are 20.4 mb, 37.1 mb, and 40.7 mb) These files are from the days we were experiencing the most saver slow downs and these journal files are much larger than the rest. Excluding last weeks journals the average file size is around 5-6 mb.

Journals usually zip up to a very small size.  Can you just create a zip and post them?

It was still to large so I attached 2 of the Journals in this post and will attached the last one in the next.

I'm seeing in the following thread that the performance issue should now be resolved:
