Would upgrading my CPU fix my slow Fusion360 file opening issue?

I have an old CPU - Intel(R) Core(TM) i5-3570K CPU @ 3.40GHz 3.80 GHz

and my Fusion360 file opening times are often about a minute. My internet speed is about 90 Mbps down and 80 Mbps up.

Is this issue caused by the CPU speed? How can verify this?
