Final Cut Pro X Renders REALLY SLOWLY

Everytime I use FCPX, it is such a pain. Whenever I do the simplest task, such as adding a title, or altering a title in the inspector, or anything like that, I get the spinning rainbow wheel of death, and it shows in the background tasks bar that it is rendering. Not to mention that it takes really long to import any media. All tasks take a long time and it is a huge thorn in my side when I'm trying to get into an editing groove. I'm on FCP 10.7 and my macbook pro specs are 5GB, 400GB, 2.53 ghz, i5. Anyone have any ideas/run into these problems?
