I should have said "autoevaluated" in the first post, since that is how I've been using SageMathCell for almost a year now. I've been careful not use any individual calculations that I know will time out and try to use the fastest algorithms possible to reduce evaluation time. I haven't seen any serious problems with autoevaluation before this.
The number of CPUs can't be the direct cause, since the evaluations just queue up and come back when a CPU is available, right? I can accept that, but when the evaluations never return it's a problem. I just retested some pages with a dozen autoevaluated cells in Chrome, FireFox and Safari on macOS. Evaluations eventually finish in the first two browsers but not in the latter. I first noticed the problem on my iPad, where pages with more than ten cells never autoevaluate. Whatever new "feature" of Jupyter is preventing Safari from autoevaluting a certain number of cells is likely what is also slowing down other browsers.
