Performance comparator between Daobab, Hibernate and JPA

Daobab contains build-in internal Json converters, which brings significant improvements.

The idea of this project is to compare the Daobab performance to various popular ORMs including the time needed to Json conversion.

The project contains an 'InternalInterceptor' - this interceptor measures the execution time contains json conversion.

However, massive invokes from InvokerService measures also an additional time needed by http protocol to establish connection and retrieve the data. That's why those time may be slightly greater that noted by InternalInterceptor.

Use Application class to run the Spring Boot application. Go to http://localhost:9001 to show the application root page. Click some links. You can refresh the page to re-run the service. Check the console logs.

The second table executes massive tests. For those tests, summary will be printed also at the web page. Every ORM need some warm-out. Because of that, each massive invoke executes the service few times before.

Some services accept url parameters for example: getCustomerPaymentSum - you can change the customer id (1 by default) at the end

http://localhost:9001/daobab/getCustomerPaymentSum/1

Also, for massive test you can change the number of invokes as below:

http://localhost:9001/invoker/testGetCustomerAddresses/100

getActors - get the complete list of actors entities getActorById - get single actor entity getCustomerPaymentSum - get the customer payment sum getCustomerAddresses - get 4 parameters from 3 tables related to customer data.
