- The plugin implementation is based on [BackgroundDownloader](https://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.backgroundtransfer.backgrounddownloader.aspx)/[BackgroundUploader](https://msdn.microsoft.com/en-us/library/windows/apps/windows.networking.backgroundtransfer.backgrounduploader.aspx), which entails the latency issues on Windows devices (creation/starting of an operation can take up to a few seconds). You can use XHR or [HttpClient](https://msdn.microsoft.com/en-us/library/windows/apps/windows.web.http.httpclient.aspx) as a quicker alternative for small downloads.
