"AMD64 Sempron 2800+ / 333FSB / 128K Cache"
I don't know much about AMD models but the FSB speed and cache amount suggests it's very a low end and/or obsolete processor. It may be second hand h/w, which isn't terrible, but you'd better hope the host has replaced the mechanical parts such as the fans and hard drive.
Another possibility at that price is that the bandwidth is oversold, you'll never be hitting your head on the 10Mbps ceiling because lots of other customers are fighting you for net bandwidth.
Post back here in a month or two and let us know what happens.
