~15 second gap in cloud run

Help
1

Hello-

There appears to be a ~15 second gap/pause at the beginning of our dbt cloud runs. The attached screenshot shows the gap in model timing. Below is an excerpt from the run log. In this example, we have 3 threads, and the log shows 3 files successfully run, then 18 seconds until the next 3 files are run.

Is this expected behavior? If not, are there any suggestions on how to close the gap?

dbt version is 1.4.5 and warehouse is Snowflake. The files on either side of the gap are base staging with ephemeral materialization. Thank you.
