SFTP and SCP extremely slow but FTP fast?
Posted: Sat May 07, 2011 9:05 pm
I had a very annoying experience when I started to download a large (700 MB) file from my home server to my Galaxy Tab. I used the SFTP and the SCP protocols at first but the download speed never went above 56 KB/s (on a fast server, almost perfect 802.11g network and the galaxy tab more or less ontop of the wireless router).
However, when I gave up and started a proper FTP server instead (vsftp in this case; it's an OpenSuse server) I immediately got download speeds of approx 2000 KB/s.
Why is that? Anyone has a an idea?
Additional info: I tried SCP to the same server from another client (Fedora in this case) at home and then the transfer speed were quite good (13 MB/s), well in line with the network capacity. It doesn't seem to be a misconfigured server.
