Is there a commercial application that will allow one to send pings at a greater frequency then 1/s? I found the shareware "TruePing" which does the trick, but was hoping to find something that had formal support. I want to perform a simple test to measure Round Trip Time on a link to evaluate the effects of increasing traffic. I need enough measurements to be statistically significant hence want a faster ping rate available so I can gather data in a reasonable time. Any thoughts appreciated. thanks!
