1. What other programs are using your
internet connection?
If you're running many programs that use
your connection at the same time, your connection is being shared and can
be spread thin. Stopping programs that use a lot of bandwidth should
result in faster transfers.
These programs include P2P file sharing
programs (WinMX, eDonkey, BitTorrrent, etc.), MP3/video download programs
(Yahoo! Music, iTunes), streaming media (online radio, movie trailers),
multiple Web browser windows, other downloads, etc.
These programs can also include spyware or adware
installed on your system (you may not be aware of this -- visit CNet's
Security Center for more information).
2. Does your ISP provide slower uploads
than downloads?
If you're experiencing lightning fast
downloads and slower uploads, check with your ISP to see what your upload
limit is. Most ISPs provide more bandwidth for downloads than uploads.
3. What is the server's limit?
You'll never experience faster transfer
than the server allows. In other words, the server limit may be your
limit. Check with the FTP server administrator for information on a
specific server.
4. Do you have multiple connections open
to the same server?
If so, you're using up more of your
bandwidth at once. Generally, this allows for faster downloads at a slower
rate per connection. This can be a perceived slowness, as the sum of all
connections can be quite fast.
5. Who else is connected to the server?
As noted in question three above, FTP
servers have a limit. If other people are connecting to the server at the
same time, it will affect your transfer speeds.
