What are some java projects (open source) that can measure performance of SELECT with PostgreSQL from master only or from master + replicas?

Question

PostgreSQL

jdbc driver can send requests to Slave:

jdbc:postgresql://node1,node2,node3/accounting?targetServerType=master
jdbc:postgresql://node1,node2,node3/accounting?targetServerType=preferSlave&loadBalanceHosts=true

https://jdbc.postgresql.org/documentation/94/conne...

That is, you can make a benchmark of how a java application works when working with postgres only with master or with master + slave.

https://github.com/8kdata/javapgperf is not suitable as it measures query times and I need TPS
