Reviewing a Xen PV VPS

This is the first time experience with XEN PV VPS. Looking at it, I found it much more better than openVZ ones. Here are some tests I have performed:
Network Tests

# wget  http://dl.dropbox.com/u/44794654/bench.sh -O - -o /dev/null|bash
System uptime :   15 min,       
Download speed from CacheFly: 11.0MB/s 
Download speed from Linode, Atlanta GA: 11.24MB/s 
Download speed from Linode, Dallas, TX: 16.0MB/s 
Download speed from Linode, Tokyo, JP: 6.11MB/s 
Download speed from Linode, London, UK: 9.16MB/s

Disk IO Tests
