Blessed GC settings for big servers

	# Base settings and GC logging
	-server -XX:+AlwaysPreTouch # First should be default, but we make it explicit, second pre-zeroes memory mapped pages on JVM startup -- improves runtime performance
	# -Xloggc:gc-%t.log # CUSTOMIZE LOCATION HERE - $path/gc-%t.log -- the %t in the gc log file path is so we get a new file with each JVM restart
	-XX:NumberOfGCLogFiles=5 -XX:+UseGCLogFileRotation -XX:GCLogFileSize=20m # Limits the number of files, logs to folder
	-XX:+PrintGC -XX:+PrintGCDateStamps -XX:+PrintGCDetails -XX:+PrintHeapAtGC -XX:+PrintGCCause
	-XX:+PrintTenuringDistribution -XX:+PrintReferenceGC -XX:+PrintAdaptiveSizePolicy # gather info on object age & reference GC time for further tuning if needed.

	# G1 specific settings -- probably should be default for multi-core systems with >2 GB of heap (below that, default is probably fine)
	-XX:+UseG1GC
	-XX:+UseStringDeduplication
