You're talking about a kernel RAMDISK and not one of those solid state
ramdrives? Performance wise, how do they compare to each other? I'm
assuming the ramdisk is the fastest because you're not going through an IDE
bus to get the data...?

And I assume postfix can handle multiple queue directories? I wouldn't
mind having a 256M ramdisk for everyday queues, and then a larger 2-3 gig
queue for the days when I lose a T3 or two. Can I preferentiate the ramdisk
over the hardisk, so that postfix won't start using the harddisk until the
256M ramdisk is full?
