Hi James,

I just want to say, great work! I tried gplpv 0.9.6 (normal install, no 
additional tweaks) on RHEL5.2/xen3.2.1 (xen.org's srpm rebuilt), and I 
got these results :
- network transfer domU->dom0 : around 70 Mbps (tested with iperf, no 
additional options). This is around 1/10 Linux PV performance.
- disk I/O : around 4 MBps simultaneus read-and-write on the same block 
device (load created with dd inside guest, performance measured with 
iostat from host). This is around 1/3 Linux PV performance.
Both numbers are lower compared to PV performance, but IMHO it has 
reached an "acceptable" level :D Great improvement when compared to 
original HVM performance.
Regards,

Fajar
