Ping to localhost system

I have multiples server with the same configuration. I am trying to ping localhost 127.0.0.1 from each servers. I am getting different response from one of the server. I get mostly following result from all the servers except one.

--- 127.0.0.1 ping statistics ---
19 packets transmitted, 19 received, 0% packet loss, time 18000ms
rtt min/avg/max/mdev = 0.003/0.004/0.011/0.002 ms

The problem is , from one of the server I get following results.

My /etc/hosts file have following line 127.0.0.1 localhost.localdomain localhost

Could you please advise what could be wrong here?

[update from commets:]

My worry is avg time per packet, that is too high in second case.

There's nothing wrong. All your packets still get through in both cases ("0% packet loss"). You're just getting more detailed output in the second case, with one line per packet (unless you're also getting that in the first case and you're just omitting it". There's just a slight difference in your settings or your operating system version.
