Re: [JoLUG-General] FTP Question

[Fadi Kahhaleh]

Hi Faisal,   Sometime ago, I had to get some info on FTP so I ended up reading part of the RFC on FTP, I could be wrong, but I do remember reading that FTP creates sockets on different ports (other than 21) behind the scenes to transfer the files, it could be the overhead of creating/deleting each socket for each file as we know FTP utilizes TCP which means handshaking overhead.   Faisal I think you can change the transfer type between two options, Passive FTP or sth… Add on top of that the IO time like my fellow friends pointed out, and I guess we Have a good explanation don’t you think!..   Just my $0.02.. and I could be way to wrong :D   Fadi .K From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Al-Faisal Sent: Sunday, June 11, 2006 12:03 PM To: Jordan Linux User Group Mailing list Subject: [JoLUG-General] FTP Question   Hey guys, I have been using FTP a lot lately to upload/download files from a web server, and i have noticed that when you download or upload one large file, it takes less time (far less time) than a group of smaller files with the same total size. Since i am not much of an expert in networking, I just started wondering as to why that happens? is that normal? does perhaps initializing the streams for every file consume that much time? I tried it using a Java applet provided by the web hosting provider, and the FTP command on the shell. Just a curious mind wondering, thanks in advance. -- Al-Faisal El-Dajani Tel: +962-7-88 719 685 P.O Box: 140056 11814 Amman, Jordan May the source be with you
