We use only at most nr_of_nodes * 2 threads for snapshot
save, considering not<br>
draining the cluster too much.<br>

I guess qemu-img use more threads and it doesn't
calculating the fingerprint<br>
to de-duplicate.<br>

</div>
<div>Repeating for the second time 'cluster snapshot save'
with '-m' option, it takes 3'37''.<br>
</div>
<div>I guess because fingerprints were already calculated. <br>
<br>
</div>
<div>Import is also a bit slower:<br>
5'05'' for 'cluster snaphsot load -m' <br>
3'43'' for qemu-img.<br>
<br>
</div>
<div>In case of selective vdi restore it's fine like that,
to avoid stealing too much resources as you say.<br>
