Slowdown

[Thomas Judson]

I have noticed a huge bottleneck on SMC in the week, especially when I am trying to grade Jupyter notebooks. Is there a problem with the system or is it just me? The notebooks are running on the paid server.

What *precisely* is slow?

Actually, I want to say that I refuse to do any support on this
problem here. If you want support, please make a support request by
clicking "Help" in the upper right with the relevant file open. That
provides us with info about your web browser, the exact file you're
having trouble with and where it is located, etc. There are a
million things that could cause slowdowns, and it's a waste of time
going back and forth without standard info. As an example, just
opening a bunch of Jupyter notebooks will very inefficiently spawn a
bunch of python processes, and if you don't kill them, then suddenly
things will bog down. (Sage worksheets use fork from a single master
process, so are much more memory efficient en mass.)

I don't know if he wanted support; it seems to me that he was checking with the community of SMC users to see if others were experiencing slower-than-usual performance. I have had days like that, when everything just seems slow. There have been occasions in the past in which you provided a definite reason for poor performance (such as a hardware issue). I think this is an appropriate forum to ask about general slowness.

I also understand your point. Support requests should be made through "Help."

As always, thank you for your rapid response to user comments, requests, and even ineptitude (I hope I'm not the only one).

It turns out he had dozens of Jupyter notebooks running at once slowing things down for him...  We need to change the ui to make this clearer.

Just to be clear - I really really want all problems that users have with smc to get resolved very quickly. Please please make a support ticket if you have issues so we can help you as quickly as possible.
