I use intellij at work, but they gave me a macbook pro with 16GB of ram and a SSD. It still manages to beachball once in a while, but the functionality is worth it. At home on my desktop (4Gb of ram and a HDD) I switched to Emacs + ensime. It has a subset of the functionality of Intellij (some refactoring, jump to definition, type inference, autocompletion) and Emacs commands are hardwired in my brain. It's lighter than Intellij, you could check it out (and add some vim emulation since you seem to be a vim user!) edit: there are ensime integration solutions for vim ( eg: https://github.com/megaannum/vimside https://github.com/megaannum/vimside )
