With the new version of the xfh handler it's possible to run DiskSpeed on a xpk
device.

This gives som interesting results.

As I usually uses Smartdisk (available on a fish disk I think) for cahcing the disk 
so that file operations when using xpk (like dir on the same directory multiple 
times) won't take to long, I've also included results with and without Smartdisk 
enabled.

The partition I tested this on was 92MB big and was approx 50% full at the time.
It shouldn't be to much fragmentented as it only containes programs which have
been installed one after another, and little editing has been done on this 
software afterwards. Most of the software had been installed using xpk.
The was formatted with DC-FFS

Ps. I didn't bother to do anything more than the MEMF_FAST, LONG-aligned test
