Using Multiple CPU Cores in DOS? (Miscellaneous)
If you really want to use two CPU cores you could find some help on forums in http://www.osdev.org
But you still will have to solve the speed on single core CPUs.
I believe that moving data from base memory into extended memory via INT 15h.87 is slow in realmode but are you sure it is slow in vm86 mode too?
Or you couls maybe requiere loaded DPMI server, if it could help, of course.
