Exactly.

In addition:


 * You know you are allocated 6 GB of memory but the server could be allocating more than it really has, and (exceptionnally) work from disk from time to time


 * You also know that you have 3.5Ghz cores but these probably are virtual cores, again with potentially more allocated than your server really has

(This is almost like being on an overbooked United Airlines flight, except you won't be thrown away by force, only that your seat would shrink dynamically...)


 * Then you don't know how "divided" is the physical server, what kind of neighbors you have and what they are doing. If they have CPU / disk intensive applications, that will impact the performance of your VPS.

This is why if you want to have full mastery of your server performance, you should use a dedicated physical server.
