I experienced the same on first time usage; however you can run jMeter 
from remote, too; actually you may run it from multiple servers, with 
the GUI on your localmachine just sending commands to the jmeter-servers 
and receiving reports from them.
This setup allows for really nice on purpose DDOSes ;-)
