A trivial one would we to :

I currently don't have good numbers that I can share right now.
Snapshots/sec depends on what kind of workload is running, and if the
guest was almost idle, there will be no snapshots in 5sec. On the other
hand, if the guest was running I/O intensive workloads (netperf, iozone
for example), there will be about 50 snapshots/sec.



50 is too small: this depends on the synchronization speed and does not
show how many snapshots we need, right?
