Results
We received the following test results on our system:
Total average execution time = 14.616670701202292
Total average execution time using pool= 8.448640361494393
The results can be interpreted as follows. When using 500 threads and the
java.util.ArrayList class, it took approximately 14 milliseconds on average per job
task when no Object pools were used. When Object pooling was used, it took
approximately 8 milliseconds on average per job task.
You can use the application to test the difference using your own classes. You
can also check how the JVM memory settings affect behavior.
