In the above example, the server will be started, and will listen on ports
9000 and 9001.
Port 9000 will be used for http access. Port 9001 will be used for telnet
access.
The startup.bsh file will be processed by the server, and can be used to
define various functions and set up variables.

As a practical example, assume you have a long-running JMeter test running in
non-GUI mode,
and you want to vary the throughput at various times during the test.
The test-plan includes a Constant Throughput Timer which is defined in terms
of a property,
-e.g. ${__P(throughput)}. The following BeanShell commands could be used to
monitor and change the test:
