Whenever there is a problem with one of the browsers, usually it is
Safari.
I think it is difficult/inefficient to say anything more without
seeing an actual page with these issues.

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.

A week ago we have updated to Sage-7.6 which means picking up new Jupyter
components
etc. So it is possible that some change in them results in slower
behaviour. Are you
taking about 10 embedded cells which are autoevaluated? Note that we have
only 4 CPU
cores, so if someone opens a page with 5 automatic embedded cells there
is already a
slow down, not to mention what happens with multiple users. So in my
opinion it makes
sense to use automatic evaluation sparingly and make users press a button
whenever
sensible. Restarting the server does not affect speed much and is
sensible only when
nodes are down (in which case they usually restart automatically). At the
moment they
are running for 3 days, and we are getting load spikes in the afternoons.

evaluate at all in Safari, both desktop and mobile.
Has something changed recently that would affect multiple
evaluations? Or
does the server simply need restarting?
