How to speed up initial sync

DRBD
1

OS : Windows 10
WinDRBD Version : 1.1.7

After configuring WinDRBD on one node, I want to connect to the remaining node after inserting the data into the Primary node.

We conducted a test using a 1Gbp network in 10G size. It took approximately 12 minutes and 30 seconds for synchronization to complete.

We actually need to sync 8T.
Based on the test contents above, it appears that it will take about 7 days for synchronization to be completed.

  1. Is there a way to shorten the above time?
  2. For other people, how much time does it usually take?

The current configuration is like this.

global {
	udev-always-use-vnr; # treat implicit the same as explicit volumes
	disable-ip-verification;
}

common {
	startup {
		wfc-timeout 1;
	}
}

resource r0 {
	net {
		protocol C;
		max-buffers 8192;
	}
	disk {
		resync-rate 100M;
		c-plan-ahead 0;
	}
	floating 192.xxx.xxx.xxx:7789 {
		node-id 1;
		device minor 1;
		disk "xxxxx-xxxx-xxxxx-xxxxx-xxxxxxxx";
		flexible-meta-disk "xxxxx-xxxx-xxxxx-xxxxx-xxxxxxxx";
	}
	floating 192.xxx.xxx.xxx:7789 {
		node-id 2;
		device minor 1;
		disk "xxxxx-xxxx-xxxxx-xxxxx-xxxxxxxx";
		flexible-meta-disk "xxxxx-xxxx-xxxxx-xxxxx-xxxxxxxx";
	}
}

Thank you for your comments.
