Graph Result is expensive to run; use Summary Report instead whilst
conducting the actual test, and reload the data for analysis later.
A loop count of 1 does not really give JMeter time to get going; there
is some startup overhead the first time elements are used.
Much better would be to use a larger loop count and use the Constant
Throughput Timer to control the rate.
Try creating a dummy test using the Java Request Sampler so you can
test things out without stressing the server or the network.
Then replace it with the SOAP sampler. BTW, the XML-RPC sampler uses
fewer resources, so use that it it works for you.
