It is a guess. I located the delays in the PHP script in the ftp login
command, and I encountered the same delays connecting to the ftp server
with FileZilla, and the delays occur only after the PHP script had been
running some times. So my conclusion was that something in my script
slows down the ftp server; I don't know much about ftp, and assumed this
could possibly be open connections that are only closed after the
timeout period. I will ask my ISP how to access the ftp log to find out
more.

Yes I also found the correct documentations in the english version of
the manual; the errors are in the german version. Sorry for this badly
researched statement.
