I don't know what you expect in terms of performance, but I guess that ActiveRecord does the handle the caching of the entities for you so you don't worry too much (except if you hit the database directly, working around ActiveRecord...) Anything specialized is usually more performant than something generic. Java is more performant than Ruby (currently), but Ruby code is usually easier to develop and maintain, so the performance cost is easily forgotten. You could draw a parallel for a workflow engine. > Shall we go with your OpenWFEru or try to build something more "Rails" Like > ? You should build a quick prototype and then decide. Maybe the OpenWFEru approach is not for you (sudo gem uninstall openwferu).
