What makes a dedicated server host smooth game servers?
I was just wondering what technology or specification usually makes game servers stutter and lag sometimes? I always thought it was the processor and the connection speed, but I have 2 servers from 2 different providers with the same processor & specs, and one of them hosts smoothly 24/7, while the other stutters for 2-4 seconds once or twice a game (a 30 minute span).
Could it be the network provider? And how can I find the smoothest providers?
