TCP/IP buffer size

[duo_core]

Thanks. Finally I have found out the problem ~> "MODE Z"

By default this option is turned on. When I switch this option off, I can reach 10MB/s again. (I mean, I try to download files from another FTP site on LAN not from localhost.)

To note that "Bypass for local (LAN) sites FTP sites" is already turned on. I think this function is broken (defect), isn't it?

I have a suggestion about File Exist Rules: We can choose different actions when the file size is larger, smaller or same. mum.. Usually if a file is small than 100kb, I always let program overwrite it. So, do you think, it might be helpful to add such an option in File Exists Rules "when File size is more/less than xxx KB"

thanks
