FTP upload speed compared to other clients...
I have a really simple script that uploads a file using ftp_put(). This script is about 10 times (!) slower than uploading the same file from the same server to the same server using Filezilla. The PHP script is as far as I can tell doing exactly the same as Filezilla, passive mode, utf-8 opt, etc. We have captured the traffic using Wireshart and the company responsible for the FTP server is currently investigating those, but I thought I'd just check in on this forum. Edit; the question is if anybody has seen this and has some advice :)
