Performance Issues. User Error or Suboptimal Hardware?

Mac Specs:

• 2.2 GHz Quad-Core Intel Core i7
• 16 GB 1600 MHz DDR3
• Intel Iris Pro 1536 MB (GPU)
• macOS BigSur

I'm a real beginner when it comes to 3D modeling. I became the de-facto engineer for my company by accident, so there's been a lot of learning on the fly. Currently I'm working on developing 3D models for parking kiosks to used for documentation. Basically developing a virtual model of an entire assembly down to the nuts, bolts, and even wiring. I suspect Fusion wasn't intended for this, but after overcoming some issues things have been progressing fairly smoothly.

However I've been working on a 2016 Mac Book pro and as the files increased in complexity, it has begun to struggle. At times I'm hitting 200-300% CPU usage. Simple actions like toggling visibility or isolating components can take 5-15 sec to process. Even rotating views can be jerky and laggy.

I'm gone through and disabled all effects as Fusion suggestions, but it hasn't helped. I've gone through and simplified models as much as I could too, but no dice. This is without any other programs open as well. So I'm wondering the following:

1. Will turning off capture history help performance in any meaningful way?
2. Is this just a result of poor optimization by me or using the program for something it wasn't intended for..... If so, are there best practices I should be employing to minimize performance issues moving forward?
3. Is this just old, less-than-ideal hardware just not being able to handle larger projects (aka new workstation required?
   
   TL;DR: I'm experiencing major performance issues with larger files. Wondering if it's caused by poor modeling etiquette or just unsuitable hardware.

@gregF29ZL - it is hard to say for certain without seeing the model in question.  The answer is most likely a combination of a bunch of factors - some inherent Fusion performance issues, some design techniques, possibly trying to model too much in one model.

If you are willing to share the design, we can take a look.

Sometimes turning design history off can help.  So can saving sub-assemblies as external designs, and re-inserting them (not always possible, but sometimes is).  Minimizing the size of sketches (pattern in the model, not in the sketch) can help.

Unfortunately due to company policy I am unable to share designs at this time.

I can give you some additional details though if that helps:

• File contains about 1500 bodies.
• 95% of these bodies are external designs.
• There are probably <12 sketches total (All being extremely simple and small)

Please share your design. As @jeff_strater indicted this can be due to quite a number of factors.

If your design uses link components, the easiest way to share the public link to it from the data panel.
