com.amazonaws.services.s3.model.ListVersionsRequest
Configuration options for how {@link TransferManager} processes requests.
The best configuration settings depend on network configuration, latency and bandwidth. The default configuration settings are suitable for most applications, but this class enables developers to experiment with different configurations and tune transfer manager performance.
