Hi!

I'm doing some tests to get an idea of how much time could be saved starting a cluster by using a pool and was wondering if the results I get are what should be expected.

We're using AWS Databricks and used i3.xlarge as instance type (if that matters).

When not using pool it takes about 3 minutes for my cluster to start. When using the pool it takes about a minute which still seems a long time to me since there is an instance up and running.

Is it what can reasonably be expected or is there some way to improve the cluster creation speed?
