public class TransferUtilityConfig

The TransferUtilityConfig type exposes the following members


Public Method TransferUtilityConfig()

Default constructor.


Public Property ConcurrentServiceRequests System.Int32

This property determines how many active threads or the number of concurrent asynchronous web requests will be used to upload/download the file . The default value is 10.

Public Property MinSizeBeforePartUpload System.Int64

Gets or sets the minimum part size for upload parts in bytes. The default is 16 MB. Decreasing the minimum part size causes multipart uploads to be split into a larger number of smaller parts. Setting this value too low has a negative effect on transfer speeds, causing extra latency and network communication for each part.

Public Property NumberOfUploadThreads System.Int32

Gets or sets the number of executing threads. This property determines how many active threads will be used to upload the file. The default value is 10 threads.
