What is the best expected starting time for a cluster when using a pool?

[PaulP]

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?

@Paul Pelletier​ usually pools are 4 times faster, pools are best way to speed up cluster creation as they overcome DBR, and Demon services are alredy been fetched. cluster auto scaling should be also fine, but pools are recommended as far as i know

One minute is pretty good. There are also differences between instance types (some are faster to start).
