I do not run any GPLPV drivers.  Performance wise between 3.3.2 and
3.4 difference as in speed and performing tasks via remote desktop in
HVM windows 2008 guest is very noticeable.  Lag time can be more than
twice just for remote desktop logins with no other changes just the
difference of xen version 3.3.2 and 3.4.0.

I might have jumped into wrong conclusion too soon though and will
test again later then report back the result.  If you have any test
tools for me to perform and compare between both versions will be
great ;)

Thanks.

Kindest regards,
