That says:
resource drbd1 {
options {
}
net {
}
_remote_host {
address ipv4 10.0.0.193:7789;
}
_this_host {
address ipv4 10.0.0.192:7789;
volume 0 {
device minor 1;
disk "/dev/vg_rabbitmq_data/lv_data";
meta-disk internal;
disk {
resync-rate 40960k; # bytes/second
}
}
}
}

That outputs nothing.
I got some hints on IRC to set c-plan-ahead to 0 to disable the variable
syncer which seemed to improve the situation somewhat in that the secondary
"wants" shows the correct value and I can slow down the sync rate but
cannot apparently get past the 5M mark. As a test I copied a file over
using scp using arcfour encryption and that happens with 97MB/s so the
network/disk bandwidth is there.
