Network has no limits, and ndis-bridge is the fastest way.
If you use raw partition of your filesystem (like 
cobd0=\Device\Harddisk0\Partition3), then Windows does not cache this. 
So, it can be slower as in native Linux.

Use "setcobd=async" to enable asynchronous mode for cobd devices.
Or, use scsi devices instead cobd/hda. Scsi driver works asynchronous 
per default.

For example "scsi0=disk,\\.\PhysicalDrive0" for the first harddisk. Be 
carefully with this option! Don't mount any partition, that is mounted 
always under Windows (for example drive C:).
