Database Software

I've been experimenting/evaluating GoldenGate replication and I keep running up against a limiting factor. If I understand things correctly, GoldenGate's extract processes monitors some of the logs Oracle spits out and uses them to generate its replication messages. However, as far as I can tell, those logs are read, at best, once a second (under heavy load, I've seen it take much longer). On the one hand, I expect there's still a great deal of tuning to be done, both on the hardware and networking side, but on the other, it severely concerns me that there's a baseline minimum one second delay for each replication hop due to a polling period from GoldenGate alone.

So the real question is: can the GoldenGate processes' polling period can be reconfigured to be quicker? I couldn't find anything in the documentation to suggest this was possible, but I'm convinced it should be.
