<li>Asynch - samples are temporarily stored in a local queue. A separate
worker thread sends the samples.
This allows the test thread to continue without waiting for the result
to be sent back to the client.
However, if samples are being created faster than they can be sent,
the queue will eventually fill up,
and the sampler thread will block until some samples can be drained
from the queue.
This mode is useful for smoothing out peaks in sample generation.
The queue size can be adjusted by setting the JMeter property
- <b><code>asynch.batch.queue.size</code></b> (default 20) on the client
node.
