This would be a useless comparison in so many ways. ext2 drivers
performs _way_ worse under windows, due to code quality. there just
aren't that many people interested in a high performance ext* driver
for windows, understandably. Also, the features of the filesystems
are so different, you can't even compare them. fat and ntfs are stuck
in the dark ages compared to ext*.
There is an in-kernel NTFS implementation, but it's no good for writing.
