ERPNext Read Replica not fully utilized

Good day,

We are currently utilizing AWS RDS with Read Replica for ERPNext. Upon checking, the primary database is experiencing bottleneck in our operations. However, the read replica’s utilization is way too low.

We have followed the proper steps as per the documentation.

Is there anything to configure other than what is mentioned? @revant_one, I hope you can shed light on this.

Thank you.
