Ever since I went from Rhino V6 to V7 I have encountered extremely long file load times. By that I mean taking several minutes to load. It seems random when this happens. Sometimes files open immediately. Sometimes it takes a long time. File size is not a driver. It can even happen when creating a new file. When I go into Activity Monitor, Rhino is marked in red as non responsive.
When I had raised this before it was suggested this was due to my olde OS. Now I have the new computer and latest OS and I am seeing the same thing.
Here’s a screen shot. While it take a long time, not a lot of CPU is being used.

But, is the slowness per file? Does the same file always load slowly, however slow that is, and other files always load normally? If the slowness is consistently per file, it would be best if we could get one of those.
Right now I am staring at a 3.5MB file that has been loading for 3 minutes. In this case it’s from a network drive but I get this slow behavior on my local SSD as well.
Is there any way to help diagnose this problem? I am finding it frequently and only in Rhino. It takes a system reboot to clear. Or I can wait a long time for the file to load. After a reboot, the load times return to normal for a while. There is obviously some operating system interaction involved.
I saw this problem on my olde Intel Mac starting in V7 and I still see it on my ARM Mac.
We’re going to need to see a file to reproduce this one. Either an example attached to a reply here or - if the file is big or confidential - then it can be uploaded to Rhino - Upload to Support
We’d love to take a look if you’re still experiencing this problem.
