If the server crashes, or generates abnormal errors then it has not
handled it well.
Or perhaps some samples take a very long time, whereas most don't.

It may well take longer to process some/all samples during the burst,
but if it recovers quickly when the load stabilises, then it is OK.

JMeter sends a request to the server, and waits for the response.
It then proceeds to do the next item in the test plan.

There are some test elements that affect many or all threads (e.g.
synchronizing timer) but in the main, each thread runs independently.
