Like DON said: It is 10% but I've seen up to 12% at times but typically it is 10% of your ISP speed.
and it depends on what's going on in your box...if you are downloading torrents into your box your ftp speed from your box to your pc slows down, sometimes quite a bit.
It's all based on the I and 0's.
That's why just renting a seedbox sucks. You have to deal with what the other renters on that server are doing too.
And almost all seedbox sellers add way too many seedboxes to a server, to maximize their profits, not really giving a shit about how it basically fucks people.
Like DON said many times before, if you don't get a dedicated server by yourself and either set it up yourself or get someone to do it for you, you're a fool.
AND it's about 3 to 5 times cheaper than renting a seedbox from any person/company.
ps: Next to this one...
