This concept is really helpful if you are trying to download a folder that has many files. Parallel downloads, also known as “concurrent downloads” is the ability to download several files at the same time using FTP.įTP Clients that support this option will create multiple connections to the FTP server to download files at the same time. The concepts are parallel downloads and segmented downloads. In this article, we will try to explain two concepts that will help you maximize the download speed from your server/seedbox to your local machine via FTP. This can be worked around by using a wired connection or upgrading to a faster Wi-Fi standard, such as wireless N. While WiFi connections may be the bottleneck in cases where old wireless protocols are used in your router. In addition, a wired connection is ideal for this. For faster download speeds, we would naturally advise upgrading your speeds at your ISP. But if there’s a big discrepancy between the bandwidth and the network delay, even that 1 MB can be too small to saturate the bandwidth.One of the most common concerns by Seedbox users is not about the BitTorrent upload/download speeds within the server itself, but rather on FTP speed in which the files are transferred back to their home/local machine.įirstly, let’s clarify that if the download speed on your local machine is 1Mbps, you can not bypass that speed.

For example WinSCP can request up to 32 chunks for 32 KB each at once, totaling 1 MB (these are defaults which can be altered with SFTPDownloadQueue and SFTPUploadQueue raw session settings). Most SFTP clients (including WinSCP) overcome the problem by both requesting/sending a large chunk of the file in each single read/write request and by sending (queuing) multiple requests without waiting for a response to previous.

If the client spends this time uselessly waiting, your transfer speed will be low. When transferring, the SFTP client (WinSCP) sends a read/write request to the SFTP server, waits for a response and repeats, until the end of the file.Įven if your connection is fast, if the server is far away (or slow), it takes a time for the response to arrive back. Network delay/latency affects particularly SFTP, as it is a packet oriented-protocol.
