- choose some process-intensive application (e.g., glean)

add following to pom.xml:
	<properties>
		<maven.compiler.source>1.8</maven.compiler.source>
		<maven.compiler.target>1.8</maven.compiler.target>
	</properties>


	<build>
		<plugins>
			<plugin>
				<artifactId>maven-assembly-plugin</artifactId>
				<configuration>
					<archive>
						<manifest>
							<mainClass>wvw.glean.cig.CIGTest</mainClass>
						</manifest>
					</archive>
					<descriptorRefs>
						<descriptorRef>jar-with-dependencies</descriptorRef>

			</plugin>
		</plugins>
	</build>


- use mvn to package jar-with-dependencies:
	(Eclipse export "runnable jar" doesn't work properly)

	mvn clean compile assembly:single


- start VisualVM
VisualVM: Applications > Profile startup (requires "Startup Profiler" plugin)

class to be profiled: e.g., wvw.glean.cig.CIGTest

- run the following in cmd:
/Library/Java/JavaVirtualMachines/jdk-17.jdk/Contents/Home/bin/java -agentpath:/Applications/VisualVM.app/Contents/Resources/visualvm/visualvm/lib/deployed/jdk16/mac/libprofilerinterface.jnilib=/Applications/VisualVM.app/Contents/Resources/visualvm/visualvm/lib,5140 -jar target/glean-0.0.1-SNAPSHOT-jar-with-dependencies.jar

(try different port number if it complains that the process is already running!)



- NOTES

lot of time spent on parsing N3 code (over half..)
comment out Log.info's in FRuleEngine, for pete's sake .. (400ms total time)

second, running transitAll -> .. -> FRUleEngine.fastInit/saturate
	processTriggerClauses (25.5%)
		-> tryRule .. matchRuleBody .. matchClauseList (20.8%)
			-> matchClauseList (11.8%)
			-> sortOnRuleBoundedness (1.4% + 0.3% + 0.3%)
	tryUniversalRules (4.5%)
	
hot spots:
highest self-time: NiceIterator.hasNext, FilterIterator.next, RuleUtil.match ..
	sortOnBoundedness: total time: 2,5s! 
		InputConstraint.check: 307ms
		ground: 1.9s
			InstantiateTriplePatternVisitor.visitNode
			..visitCitedFormula: 1.6s
			..visitCollection: 1.4s
			
when using compound-term-caching in visitor:
	 much less time spent on visiting collections, cited-formulas
