Good Afternoon,
Since July 25th, I have been experiencing significant delays when running Jupyter cells, even for those containing only commented-out code. The execution sometimes takes several minutes and, in some cases, does not complete at all.
Initially, I suspected the issue might be related to the R-MICRO node, so I purchased a dedicated one. Unfortunately, this did not resolve the problem, as the substantial delays in running cells and difficulties in initiating and connecting to the Python Kernel persisted.
Could you please let me know if QuantConnect is experiencing any performance or stability issues? Additionally, do you have information on when these delays and outages might be resolved?
Thank you for your assistance.

Hello Dmitrii,
I'm sorry to hear about the issues you're experiencing with the Jupyter notebook in the Algorithm Lab. There have been similar reports from other users experiencing slow execution times and connection issues with the Jupyter server.
The QuantConnect team is aware of these issues and has been working on solutions. For instance, they have identified and fixed a RAM leak that was causing some of the problems. They are also working on a RAM reporting system to let users know when they're approaching maximum RAM usage, which could be causing the kernel to shut down unexpectedly source.
In the meantime, if you're running a local Jupyter server, you might want to check if the server is still running and if your network connection is stable. If you're running a notebook and it's taking a long time to execute a cell, it could be that the operation you're performing is resource-intensive and is taking a long time to complete. If this is the case, you might want to consider optimizing your code or using a more powerful machine source.
If you're still having trouble, you might want to check out the QuantConnect Documentation and the QuantConnect Forum for more information and examples.
I hope this helps, and thank you for your patience as we work to resolve these issues.
