Extremely slow response when trying to run a model

I am testing a model, and the response is extremely slow. Every time I attempt to run a model, the blue circle will delay for 10-20 seconds.

Hi Bruce–

We saw some slowdowns with the “non published” sims yesterday around 9AM ET. This is the default settings for newly created sims. This should have been solved soon after your message. Did the problem go away?

Best WILL
