knownhost vps

i am planning to buy knownhost vs1 plan, so i was wondering does anyone has experience with them and that plan. here is what i want to know:

- do you host more than 5 sites with 5k+ visitors daily and is there overload of the cpu?
- is the 192mb ram enough for the traffic mentioned above?

i guess that kind of traffic shouldn't cause too much load of the server, but please share you experience
