What do you mean not the best performance? RAM behaves better in performance than other RAM?
Because since I put in another 2GB in slot 1, and have the original 1GB RAM in slot 2, my iMac and Snow Leopard is running very fast and smooth, and I am very happy
No more slugging along, even when I have 12+ applications open, and browser windows, it's running smooth and fast and no swap page is bieng used.
However, I do find that youtube videos play jerky when I have lots of browser windows and apps open, anyone know why? And is there a solution besides closing everything down? Why can't flash handle it playing smooth youtube videos when lots of apps and windows are open?
