[Planetlab-users] destinations per second

[Larry Peterson]

I have been hoping that someone else with more experience running
lots of pings would respond, but maybe you are the first to ping
so many non-PlanetLab nodes.

We do not currently enforce the unique destination limit because
it's clear how it should be set. I do know that there will sites
that choke on so many unique destinations. That worries me. Have
you looked into using ScriptRoute to run your experiments? It does
the most comprehensive job of constraining probes so as to not
upset the neighborhood.
