Object Graph

Below is the object graph of the class to be injected in the benchmark program

Object
└── A
    └── B
        └── C
            ├── D1
            └── D2
                └── E

All injection is done through Constructor injection

How to run the benchmark

You need JDK8 and maven to run the benchmark program.

The project defined two profiles: runtime and split_startup.

#Run the `runtime` profile:
mvn clean compile exec:exec -Pruntime

This will run the Runtime benchmark, which fetch the bean of class A (as shown above) for 50K times

#To run the `split_startup` profile:
mvn clean compile exec:exec -Psplit_startup

This will run the startup benchmark, which initialize the injector and load bean of class A for 5K times.

To tune the warm up and iterations:

#For startup benchmark:
mvn clean compile exec:exec -Psplit_startup -Dstartup.iteration=100 -Dstartup.warmup=10

#For runtime benchmark:
mvn clean compile exec:exec -Pruntime -Druntime.iteration=1000 -Druntime.warmup=100

To benchmark singleton injection:

mvn clean compile exec:exec -Pruntime -Dsingleton=true
