Ping is simple utility which Pinger uses for analyzing the connectivity of nodes. Sometimes the* *problem is that many hosts do not give high priority to pings and many block it. This results in high RTT for pings. It is a big difference for closer hosts than far hosts.In order to find the difference if exist, we recorded response time of pings vs HTTP hosts from SLAC to other hosts. see here* Sheet
Interesting We found that the relative difference is quite small. Relative difference is a ratio between ping time and HTTP time responses.
...
Differences are quite small as we can see from x-axis bin intervals. More over, most of the nodes are having 0 difference between ping minRTT and HTTP minRTTwhich minRTT which confirms that there is no such significant difference occurs if we use ping or http.Most of the HTTP.
70% to 94% of times the relative difference lies between 0-0.04 which reflects that ping RTT and HTTP RTT doesnot show much of the difference.
