Does the ConfigureAwait really matter?

[doggy8088]

I see almost all the examples on TestContiners docs are append .ConfigureAwait(false) to all Tasks. For example:

await Image.InitializeAsync()
  .ConfigureAwait(false);

await _weatherForecastNetwork.CreateAsync()
  .ConfigureAwait(false);

await _msSqlContainer.StartAsync()
  .ConfigureAwait(false);

await _weatherForecastContainer.StartAsync()
  .ConfigureAwait(false);

Is that really matter to the performance?

Well, it may look cumbersome, but we do not need to return to the calling thread and wait until it is ready. I am just used to set it everywhere (expect UI, etc.). Here is a good talk that covers the topic as well.

I know what it is. I'm just thinking that might not a big deal. The threading issue seems a little bit overtuning.
