What's kind of the average launch time for a SageMaker Studio notebook?

Hi Yann,

Typically you should be using the fast launch instance types, which is designed to launch under 2 minutes. Generally it is 5-10 times faster than instance based notebooks.

Here is to documentation which states so: https://docs.aws.amazon.com/sagemaker/latest/dg/notebooks.html.

Hope it helps!
