loopback testing?

Hi Experts,

We have a CM pub & sub assigned to diff. vlan on our Core switch i.e. vlan 10 & 20.

When we do a ping to loopback, say 127.0.0.1 , the result is 10ms. both server have the same result.

Also when pinged it's own ip & gateway, 10ms still.

Now we tried our pc, where it belongs to vla 5, which gives us 1ms which is normal I assume.

Could the result of the 2 CMs abnormal?

Verifying Enabling of Remote Loopback Testing:

To verify the loopback status of the current interface, after the far end has been put in loopback mode, enter the command show service-module serial replacing with the slot and port number of the serial interface.

it's the CM server not the Router.
