I’m trying to help someone with slow performance issues with models that they make. They use the PlusSpecs extension, which I think isn’t part of the problem, it just happens to be a quick way to create a scene with quite a lot of components in it.
I have their model and can certainly see problems, even without me having that extension. I can’t really send the model, it isn’t mine, but hopefully my description of the issue will be enough.
The model is not a very large one. It does happen to have 31 scenes, but even then the skp is under 7 MB. In my tests I made a single scene version, and that is 3.8 MB. The number of scenes may be important.
The main symptoms are that it takes a long time to open the file, and when working on the file SketchUp sometimes needs to be force quit, because it becomes that locked up.
For my test I opened the model, eventually, was then able to whiz around in the scenes without any performance problems, then I would do a Revert. I gave up after 20 minutes of waiting for the revert to finish. By that point SketchUp was using over 128 GB of memory. Here’s part of Activity Monitor:
My single scene version of the model opens quickly and reverts immediately.
I tested under Windows 10 as well, still on my MacBook Pro (which at the time had 15 apps open) using Parallels. The problem model opened as quickly as my single scene file, and it reverted as quickly as well. The memory used by Windows 10, which would include SketchUp, was under 3 GB.
So, it seems to be Mac specific, and the number of scenes may be important.
Does this sound like a familiar problem to any of you?
