I'm still in the process of testing and optimizing different applications and environments on the T1000. Why? Because there really are a lot of options available to you once you start looking and even more if you start approaching the problem in different ways.
One of the key things with the T1000 is that with the multiple cores and multiple threads getting the best out of it takes some work. Some applications simply don't scale well with multiple threads (and I point no fingers), so instead of looking at one big application you look at running the same application multiple times. Rather than running one version of the Apache, for example, try running 4 versions and allocating them a quarter of the CPU core allocation each, and then let them get on with it. The RAM requirements are higher (slightly) because of the overhead, but when you have 8GB or 16GB to play with, and extra couple of MB is not the primary concern.
