  edu.umd.cloud9.io.BenchmarkPairOfInts

public class BenchmarkPairOfInts
extends Object

Benchmark for PairOfInts. Does the following:

• Creating 2 million new objects. Each is populated with two random numbers between 0 and 1000. All objects are added to an ArrayList.
• Cloning all 2 million objects. All new objects are added to another ArrayList.
• Sorting the second ArrayList

See below for results comparing this benchmark to BenchmarkTuple and BenchmarkJSON (on the equivalent task). All times measured in seconds.

	PairOfInts	Tuple	JSON
Creating objects	0.609	3.319	4.472
Cloning objects	0.576	2.303	4.972
Sorting list	1.681	7.591	11.644

Times were arrived at by taking the average of 10 trials. Experiments were conducted on Aug 6, 2008 on a 2.6GHz MacBook Pro running Windows XP and Cygwin.
