Dear Promox Team,
first of all thanks for the great work, as always!
Is it normal the live-migration performance is way slower then before? Im using local discs and
"qm migrate 107 hostnamehere --online --with-local-disks" for example to migrate a vm. The copy itselfs is fullspeed (gbit) as before, but the downtime time seem to increase alot.

2017-07-05 04:52:36 migration finished successfully (duration 00:04:34)
It says 71 ms but it seems to take the time from 2017-07-05 04:52:19 to 2017-07-05 04:52:31 to get it started on the other node (or set its power state?), so its ~12 seconds instead <100 like before.
Can you confirm this and is there anything i can change about it?
Kind regards
