How Do I Improve the Query Speed of My RDS Database?

The following are some suggestions provided for you to improve the database query speed:

View the slow query logs to check whether any slowly executed SQL queries exist and view their performance characteristics (if any) to locate the cause.
View the CPU usage of your RDS DB instance to facilitate problem locating.
Create read replicas to offload read pressure on the primary DB instance.
Add indexes for associated fields in multi-table association queries.
Specify a field or add a where clause, avoiding full table scanning through the SELECT statement.
