RemoteJMeterEnginelmpl: Starting backing engineIf you do not see this message, it means jmeter-server did not start correctly.

RMI cannot communicate across subnets without a proxy; therefore neither can jmeter without aproxy2. Since jMeter sends all the test results to the controlling console, it is easy to saturate thenetwork IO. It is a good idea to use the simple data writer to save the results and view the filelater with one of the graph listeners3. Unless the server is a large multi processor system, in most cases 1-2 clients is sufficient tooverwhelm the server4. A single JMeter client running on a 2-3 Ghz CPU (recent cpu)can handle 300-600 threadsdepending on the type of test. (The exception is the webservices). XML processing is CPUintensive and will rapidly consume all the cpu cycles. as a general rule, the performance of XMLcentric applications will perform 4-10 slower than applications using binary protocolsAdditional resourceshttp://wiki.apache.org/imeter/jmeterfaq#howtodoremotetestingthe.27properway.27.3fhttp://imeter.apache.org/usermanual/remote-test.htmPsIn some cases, the Firewall may still be blocking RMi trafficSymantec Anti Virus and FirewallIn some cases, Symantec firewall needs to be stopped from windows servicesopen control panel2. open administrative tools3. double click services4.
