Yea. Already. If I'm using Mac OS partition to load it takes less than 10 sec to load (mac os desktop) on ssd. If I'm using Windows partition it takes some minutes with gray screen before Windows start to loading. Macbook bootup sound, then a couple minutes of waiting with grey screen and then windows partition/usb dvd starting. Same problem with rEFIt. It loads fast but when I'm chosing win/usbdvd it hangs for long time before startup.
Try setting your starup disk via System Preferences > Startup Disk
Looks like macbook is initialize superdrive but how to disable it or how to cheat it
