Do you mean the JMeter master? i.e. client?

If there is one sample in the test plan, then this will generate 10000 samples.

10000 samples in 2000 seconds is 5 samples per second.

You'll need to add a timer; easiest is probably to add a

It's all described in the documentation:

http://jakarta.apache.org/jmeter/usermanual/get-started.html#non-gui

It's a lot easier than client-server mode...

Is this to simulate 10000 different users?
In which case you do want to load the images - and other embedded
resources - each time.
