[DRBD-user] drbdadm verify speed

I am trying to use drbdadm verify resources and I can only get 60Mbps data
rate. I am using infiniband and my syncer rate is 500Mbps.

Is there any setting that I can change for the verification to happen at the
full bandwidth speed? I want to use the full bandwidth for verification.

Conf file

global {
usage-count no;
common { syncer { rate 500M; verify-alg  md5; } }
resource r7 {
protocol C;
handlers {
pri-on-incon-degr "echo '!DRBD! pri on incon-degr' | wall;
/etc/init.d/hearbeat stop ";
outdate-peer "/usr/lib/heartbeat/drbd-peer-outdater";
on ninja1 {
device /dev/drbd7;
disk /dev/loop0;
meta-disk internal;
on ninja2 {
device /dev/drbd7;
disk /dev/loop0;
meta-disk internal;

net {
