BlkCivic I understand where you're coming from and I've fallen victim to the same conundrum: trying to find the fastest Seedbox on uploads. May I ask what tracker you are basing your speeds on? The reason I ask is because when I first started out on
SCC I was only averaging a 20-100 KBps up on new torrents on my first seedbox. So I began to question whether or not it was the seedbox and set out on trying out other boxes. Since I first joined TI I have probably tried out somewhere between 5 and 8 different seedbox providers.
What I have found is that the quicker you can get on a newly uploaded torrent the more likely you are to upload at faster speeds. Kind of makes sense right? The faster you get the torrent the more likely a peer is going to go to you for the data. This became even more evident when I began using Autodl-irssi. Now on
SCC I average MUCH MUCH faster upload speeds because I get in so early on the torrent and I have more of the data available compared to others.
Also, in my different trials I found that some providers definitely oversell their boxes which inevitably leads to slower upload speeds. Common sense, there's only so many resources to go around on a seedbox when shared amongst several users so there's no real guarantees. If you want guarantees you will have to shell out the big bucks for more dedicated servers.
Now my two cents won't be complete without a recommendation, and so far I am happiest with
SeedRootS - Welcome Page. The service and support is impeccable. <3 Lardo. The only downside here is it's only a 100Mbps box. If you want gigabit I'm having some good luck with Hostingsharedbox.com on their B3000 box. If you want more insight into other boxes I've tried feel free to PM me or find me on IRC.
On another note, what are you looking to accomplish with your seedbox? Are you looking to just buffer your account or fix your ratio? I've found, and there are probably people who would disagree with me, that ratios come moreso with time than the speed of your box. The longer you seed a torrent the more likely your ratio is to go up. I have one particular torrent that I've been seeding since it first hit the scene. (Inception 1080p). To this day I have a 400+ ratio on it with terabytes of data moved from a 100Mbps box.
