StartWind iSCSI Initiator 5.6 slow synchronization

I have two iSCSI target servers and a client on 1gbps switch with Jumbo frames enabled.
Created RAID-1 Mirror, however the synchronization speed is too slow (13MB)
Networking is good as i see 70MB usage while doing Target to target replication.
Tested on another set of servers, looks like synchronization has some sort of network usage cap.

Do not use initiator-side mirror. This feature is deprecated. Please stick with a target-side MPIO-based HA. Thanks!

Thanks Anton, I'll consider your suggestion. [Tested on another set of servers, looks like synchronization has some sort of network usage cap.]
Can you tell me if there is some sort of network usage cap?

There are no limitation applied. So as it's point-to-point expect to have 1/2 of the network bandwidth maximum. Either way not supported for production.
