Research responsiveness

Show Q Research

Am I the only one that feels Research environment lacks responsiveness?

It has been always like this but some days Research it is very difficult to use so I decided to write this post.

Compared to Algorithms (that is perfect), the Research platform:
- fails to load some (too many) times
- once you start/interrupt/restart/save a cell it takes second (sometime 5, other times 10 or 20) before you see the action executed. This happens very often

Just wondering if I am the only one experiencing this.

By the way, it's not a big deal, but Algorithms platform is so fast/immediate that it feels weird Research behaves so differently. So I just wanted to check out if it's the same for the other users.

Hi Luca,
I'm thrilled you think the IDE is responsive, we spend a lot of time focusing on performance there.

As for research, it's it's definitely something we are still working on. There are couple of issues that you mentioned.

  1. fails to load some (too many) times
    When this happens, does it fail to load entirely? Or if you refresh does it load? Please send an email to [email protected] when this happens so we can help debug. Obviously this shouldn't happen.

  2. once you start/interrupt/restart/save a cell it takes second (sometime 5, other times 10 or 20) before you see the action executed. This happens very often
    One of the user experience challenges I have noticed with IPython (and our research platform) is knowing when a cell is executing and something is happening. The only change you'll notice is the cell number (on the left hand side) switching to an * instead of being a number. Outside of that, you almost never know when something is running. I think we need to make this more clear, and will include it on the list of things to do in the future.

With that said, I am not sure if that's the issue you are having OR if there is something more than just knowing when a cell is running. I'd love your thoughts on that as well.

Hi Karen,

thank you for your reply. I'll clarify the two points:

1 - When I open Research I can see a big "Connecting to Reasearch..." but sometimes it doesn't connect and you are left with a blank page (except for the menu on the top)

2 -I am aware of when a cell is executing and I can see that it takes seconds before any action (e.g. interrupting a cell) is executed. But is not like that all the time. I'll pay more attention when it happens again, so that I can be more specific.

I've noticed lagginess on interrupting a cell as well sometimes. Will keep an eye out on it myself.
