That all depends on many factors. We have recommended player slots with each of our packages which guarantees that you will be able to fit X amount of players on each as long as you don’t have any stupidly un-optimized addons.
Every recommended player slots package is tuned for a moderate setup on an intensive game-mode like DarkRP / many usual addons at 15-22 tick-rate.
No other host guarantees proper performance without you actually buying a machine. They simply sell by player slots which means that they can oversell onto one machine all they want without consequences. We cannot do that for example.
What I will tell you is that you will get equal performance with us with a more stable platform as this is as close to a dedicated machine without you paying in the 100-200 USD range.
