Slow connection speed between cube and superset

We are currently running cube in a docker container on an aws ec2 instance with centos os. Superset is running in another instance in a docker container.

We are facing significantly low speed when running query from superset to a cube table thorugh sql api. Superset is performing relatively very fast when connected to other self managed postgres instances.
