Have a try of it anyway with the RAM Drive and see how it goes compared to hard drive access. If it is a lot quicker then you will know that is where the problem is and not something else it's doing in the back ground.
I would think it would read the RealTrack info from the particular instrument's XT2 or ST2 calculating what is best then load those sections from the associated file/files in the RealTrack instrument folder. The RealTrack files are different keys as far as I can remember so it should only be working with one of them at a time. The time might be spent calculating or something else rather than reading the file sections to RAM ???? That's why it might be worth trying the RAM Drive first see what difference it makes.
Also I don't know if it was mentioned above anywhere, but check the Speed up Generation...settings in RT Prefs.
