Total Time Exception of Linux System ping Test

Problem Phenomenon:

The delay is not high when ping the target address, but the total time is very high. For example, in the following figure, test ping 4 packets for JD Cloud. Each packet is basically within 35ms, but the total time is over 3,000 ms, and execute:

ping -c 4

Cause Analysis:

Actually this is due to the fact that there is 1s interval at each ping packet, which is normal.


The interval can be controlled by -i parameter. For example, test as the same, by specifying -i 0.1 parameter, you can see that the total time is significantly smaller. Execute:

ping -c 4 -i 0.1
