Extended RAC - latency on real systems

Hello experts,

I'm doing small academic research about Extended RAC and latencies, could anybody send me round-trip-tipe average latencies (with distances and interface types) observed between distributed nodes? Preferably measured using ICMP ping with standard packet sizes and bigger ones (up to MTU, e.g. ~9000 for Jumbo Frames, on Linux it's the "-s <size>" argument). Last two lines of /bin/ping would be pretty enough...

Thanks.
