Currently we are using ZFS replication between nodes in the cluster for HA which appears to be single thread.
Have looked around and found a setting but not really within the PVE documentation to set max_replication_jobs in /etc/pve/storage.cfg but does not seem to make any difference.
The other option if it is not possible would be an option to prioritise specific jobs which I could not see.
Appreciate some may say use CEPH and we may consider this in the future when we upgrade servers and move to 100 or 400 Gig network but currently for our scenario the speed impact on writes is to high (again maybe this is where more time we could improve this).
