sphere is single thread, but since UO is lightweight and doesn't require huge network bandwidths, this should not be a problem

10 years ago we had servers running 1000 clients without problems (or maybe even more, I can't remember) using old sphere on old hardware. And since sphere, hardware performance, and hosting plans evolved through these years, they became even better, faster and cheaper

unless you have an really heavy coded server, in this case you will need an faster CPU because most of sphere CPU usage comes from internal engines (NPC AI processing, scripts processing, etc) and not from client packets processing
