Weird. I’ve been doing fine with 4GB of RAM on my MacBook Pro. Just took a look and Xcode 4.3.1 is using ‘only' 311MB of private memory, the iOS simulator is using 3.5MB, and I’ve been doing a fair number of large builds today. I don’t use Safari, but Chrome is using 123MB for the browser itself and between 10-25MB per renderer (tab) process.
Are you building large C++ projects by any chance? It’s been my experience that large C++ builds have always created tremendous memory usage, both by the compiler processes, the linker and Xcode itself. For instance building Chrome takes at least 16GB of RAM if you don’t want to be bogged down in VM thrash.
