JMeter distributed testing and command line parameters

Use -G instead of -J for properties to be sent to remote machines as well. -J is local only.

-D[prop_name]=[value] - defines a java system property value.
-J[prop name]=[value] - defines a local JMeter property.
-G[prop name]=[value] - defines a JMeter property to be sent to all remote servers.
-G[propertyfile] - defines a file containing JMeter properties to be sent to all remote servers.
