RAMDRIVE is not a disk cache, it's a RAM disk.
I also don't understand what does ``twice as fast'' means. Twice as
fast as what? In your original message you said that Linux is 10
times faster than Windows 95. My experience with well-tuned
DOS/Windows systems is that they are about 40% slower than Linux on
the same platform.

This can only happen if your program doesn't do much except
reading/writing large files, or if you use disk I/O inefficiently. It
might be a good idea to describe in more detail what the program does.
