Connect and share knowledge within a single location that is structured and easy to search. I'm downloading from a server and downloads are maxing out at 1. So why can't I download just one file at faster than 1. I know that I can use some other SFTP client that supports segmented downloads such as lftp, know of other good ones that are open source?
But I still want to know what is it that limits downloading one file to just 1. I checked and for sure there's no traffic throttling enabled at all for FileZilla. So at 1. If someone has a good explanation of why transfers peak at 1. Server is running OpenSSH 6. UPDATE: In response to Martin's information see his answer below I am adding that ping is ms to ms pretty constant between server and client that is downloading. I tried with latest version winscp 5.
Whereas if I start a secondary concurrent transfer in Filezilla I get constant 1. So could the ms delay to the server be a mathematically limiting factor as Martin and Michael touched on a bit? Or could there still be something else to blame such that I can improve the throughput?
If not, I'd appreciate if anyone knows any other like lftp but runs well on Windows open source downloader that is secure and supports segmented downloading. When downloading, the SFTP client sends a "read" request to the SFTP server, waits for a response, appends returned data to a local file; and repeats, until the end of the file.
Even if your connection is fast, if the server is far away or slow , it takes a time for the data to arrive back. If the client spends this time uselessly waiting, your transfer speed will be low. Most SFTP clients including FileZilla and WinSCP overcome the problem by both requesting a large chunk of the file in each single "read" request and by sending queuing multiple "read" requests without waiting for a response to previous.
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. An underlying TCP protocol can suffer a similar problem. See also Bandwidth-delay product on Wikipedia. I do not think this is your trouble either, at least if you have used the latest version of WinSCP for the tests. There have been some improvements in the recent releases, which allow WinSCP to utilize high-latency connections as efficiently as FileZilla.
If you have a relatively slow CPU, comparing to a large bandwidth, the transfer can be capped by your CPU being unable to encrypt or decrypt in case of the download the data as fast as your network is capable of transferring them. Use the Windows Task manager to see, if one of the cores is utilized to its maximum during the transfer. WinSCP does not utilize all available bandwidth. How do I improve the transfer speed?
Apparently even if you "disable" it, all it does is not enforce rules but it slows down network stack. Sign up to join this community. The best answers are voted up and rise to the top.

If you find that you are getting failed transfers or your internet connection is too slow for your other tasks whilst transferring files then lower the number of concurrent transfers in FileZilla.
