It depends on a number of factors. If you want robustness (so one website doesn't trample on another) then yes, multiple instances will help - and give you a separate CF Admin for each instance. But you also need to consider the number of CPUs and the amount of RAM on your server (assuming you're talking about everything on one server). You'd need to experiment, performance-wise, but I'd say not to have more instances that you have CPUs for example. We have two instances (each with a 2-3Gb JVM heap) on each of our 8 CPU, 8Gb RAM servers but then we're running a very high traffic site (up to 20,000 concurrent sessions during peak traffic).
