The linux kernel is very good at caching file accesses, so a RAM disk would most likely make things slower by reducing the RAM available to the kernel. The kernel is in a unique position to make intelligent decisions about how to divide RAM between applications and disk cache at each and every moment.
Run 'free' in the terminal to see how much RAM is used for caching at the moment ("buff/cache" column). This RAM is used for disk caching and at the same time it is available for application use if necessary.
