Raw NTFS disk access is slow. Faster?

When I access a NTFS raw disk from a virtualized WinXP, I get 10-15 MB/sec or so. It is quite slow. Is it possible to get faster speeds somehow?
I use Solaris 11 Express as host.

What is the speed you get when you mount NTFS on the Host side? You should have ntfs-3g available and installed in order to read NTFS partitions. How old is the hard drive, is the Host on the same physical device and how busy is the Host with it?

At the very end, there is more infomration:

Anyway, I am not using ntfs-3g, because it is slow. It gives me 3MB/sec. With raw disk access to NTFS partition, I now get 20MB/sec with Win7 guest. I get 10MB/sec when guest is WinXP.
Is it possible to speed this up?
