For test we run only 2 VM (RDS/TSE) with 2vcpus for each

vmstat 1 during the slowly function :

top : during the function, top for the KVM where the function
runs increase from ~50% to 130% and decrease to ~50% at the end of the
function.
In Windows, we see that one CPU is used.
The CPU in this KVM server runs at 2.3GHz (in the vmware
server, cpu runs at 2GHz).
For kvm_stats, I mean it's better to have only one VM with one
user for the test so I send this evening or tomorrow morning.
David.
