This topic describes the cmdlet in the .6.19 version of the Windows Azure PowerShell module. To find out the version of the module you're using, from the Windows Azure PowerShell console, type (get-module azure).version.

-ConcurrentTaskCount<Int32>

Specifies the concurrent network calls. By default if no value is specified for this paramater, this cmdlet initiates network calls up to eight times the number of cores available for concurrent tasks on your computer when you upload files to Windows Azure storage. For example, if your computer has four cores, the cmdlet initiates up to 32 (eight times of 4) network calls at one time. You can use this parameter to limit the concurrency to throttle local CPU and bandwidth usage by specifying the maximum number of concurrent network calls. The specified value is an absolute count and is not multiplied by the core count. For example, set ‘-ConcurrentTaskCount 1’ uploads or downloads in sequence without any parallel network request. This parameter can help mitigate network connection problems in low bandwidth environments, such as 100 kilobits per second.
