If you're only publishing to DC1 at 1.5k/sec, I'm not sure how its possible for DC3 (which is just a replicated WAN site) to have a higher throughput. Since DC2 is about 200/sec, I would expect its queue in DC1 to be growing. It would be interesting to see if thats true. If the configuration is a star pattern (every site to every other site), then batches of events won't go DC1 -> DC2 -> DC3. They'll go directly from DC1 to DC3. The GatewaySender is smart enough to not send an event to a site it has already been sent to.
How are you measuring the throughput? I'd like to see the configuration as well as the stats for all three sites.
