<ch_title>Open Model Thread Group</ch_title>

<p>New component: <code><a href="./usermanual/component_reference.html#Open_Model_Thread_Group">Open Model Thread Group</a></code>
allows creating load profiles with variable load.</p>

<p>For example, if you need to gradually increase load from <code>0/sec</code> to <code>10/sec</code> during <code>minute</code>
you could previously use <code>Thread Group + Timer</code> combinations. However, then you need to compute
the expected number of threads, ensure they are created only when needed, and so on.</p>

<p>With <code>Open Model Thread Group</code> you can configure the same load profile as <code>rate(0/sec) random_arrivals(1 minute) rate(10/sec)</code>.

by the built-in Java based one. To choose the Java based one, set the JMeter property <code>jmeter.regex.engine</code>
to the value <code>java</code>.</p>
