Q. My FTP Speeds are slow, what can I do?

There are four most likely causes of slow FTP, by order of probability:
 * 1) FTP Client. You aren't using a multisegmenting client
 * 2) Peering, your ISP has a bad route to your seedbox provider.
 * 3) Your seedbox provider is crowded, network or hard disk
 * 4) You have speed issues on home machine, wireless, hard disk, etc.

Without any information beyond "it is slow", there is no reasonable answer. For example peering is personal, what works for one person might not work for you. Same thing, if it is a problem at home.

Like asking "What is the best way to get to my house?" without anyone knowing where you live.

First, switch to a client BitKinex or CuteFTP. You don't state your client, so how can we know? When switching to either, use the multisegmenting features, and check your speeds.

Second, you can test your peering, see if the road home is screwed:

You don't state who your current provider is, but these days many providers have a reroute tool

Third, test your provider, use iperf & dd to see what network speeds and disk speeds are possible.

You can also use iperf from home to your seedbox, see this link:

On your slot:

Then run Iperf from home, first single threaded, then multi-threaded

If it turns out that switching vendors is the approach, go with one that has premium bandwidth and rerouting. Most reputable vendors provide test files, you can test your down speeds before signing up, do that.

Without doing any of these things, you are just taking a shot in the dark.
