I'm currently playing with a script to measure average ping times between some sites and have tries a variety of the ping options, but I have noticed some curious behavour.
If I flood ping for 1 second with: ping -q -n -f -w1 <target> then it appears to put out around 100 packets, I get quite high packet loss and a ping time average around the same as for a normal ping. If I war ping with 100 packets in 1 second with: ping -q -n -c100 -i0.01 <target> then I get no packet loss and a similar ping time when the target is a PSTN connection. Now here comes the odd bit. If I take out the -q option so that I can see the responses, then from ADSL to PSTN the ping times marginally increase during the sequence. From ADSL to ISDN the ping time increases by a factor of around 2 from start to end. From ADSL to ADSL however this ping time increases steadily over the 1 second by a factor of over 15.
