As title, I tested in more than one Windows 10 professional edition and Windows 7 ultimate set up IIS FTP, then use Intranet and three other Windows devices to download, download file size is about 1 gb, there can be found at the same time two computers to download, third download progress is motionless, can only wait for the first two sets of any a download is complete, the progress bar will go,
Then, I also did a test, use a computer to download the FTP three files at the same time (not one after the other downloads, but at the same time download 3), found that also is only the first two, the third front can only wait for any one over to the next,
Then again, I change with an open source FTP server, FileZilla server to do the test, there is no this problem, a single computer multiple tasks at the same time download is normal, 3 computer download together also is normal,
So, this problem should be IIS FTP, caused by some of the restrictions, then, how to improve the maximum concurrent IIS FTP download? Still say this is a server version of Windows? Because some workplace is only suitable for use IIS, cannot use FileZilla Server, please master guiding,

How to improve the most FTP transmission speed? FTP and website to download and upload was in fact a truth, if it is for FTP transmission via the Internet to improve the bandwidth speed can! Then use FTP is redundant transmission via LAN,
Commonly used way is: system usually is the default limits the bandwidth of the 20%, although not to use too much of a difference, but for the FTP
Still has a certain speed difference, bring up the run> box type gpedit. Msc> sure, open "group policy" window "local computer", and, in turn, double-click: computer configuration>> network QoS management template packet planning process, then double click on the right side of the window in the "restrictions may retain bandwidth", check the "enabled", the "bandwidth limitations" in 20 to 0, "sure", after the restart,

Thank you very much for your answer, but I met problems, not FTP transmission speed limited, is a limited number of concurrent downloads, such as I want my FTP server supports more than three at the same time to download the client, use iis set up FTP can't do that, the third landing the client have to wait before two of the download is complete to be able to; And filezilla server to open the service side, there is no this problem,
