Benchmarking tools for JupyterLab
This project is a place to make JupyterLab faster. For now, we want to optimize for various notebook content:
Opening a new notebook.
Switching tabs. An acceptable time is 300-500 ms switch time.
Closing a notebook
The following is out-of-scope, but could become later in-scope:
Initial server start.
Initial HTML page loading.
Notebok saveing time.
We iterate in steps:
Build benchmark tooling to have a baseline and be able to compare with fixes.
