I like how easy it was to install this software for our project which had many layers of complexity with large amounts if data points in each layer! As far as performance goes - not much issues at first but we did have some lag time when dealing big files or very complex sets (which were only used once).
It's worth trying out though because there aren't too expensive compared what you get back!! We're using FxCop Compiler Optimization toolkit features such as Code Analysis tools etc however due its size i cannot go through them individually without taking forever so will update later after completing my work :).
