Oh and you can try out the removal of jupyter with this setting if you want:

"python.experiments.optInto": [
        "LocalZMQKernel - experiment",
    ],

[rchiodo]

Yep that’s what I meant. Glad it worked 😃

We might be able to figure out some way to detect this (or maybe just always set the ip that way and see what happens).

However in the near future we’re about to eliminate the need for jupyter at all for all connections we generate ourselves (so this shouldn’t be a problem for anybody anymore).

The slowness is kinda ambiguous.

Is the window slow to open? (That can happen on remote ssh as we have to stream the javascript to the UI) Is the server slow to respond? (That might be a wait for idle problem we have with jupyter, that the aforementioned removal of jupyter will fix). Is it slow to execute a cell? (This one I’m not sure what the problem might be)
