Properly designed and configured replication
environments, especially on 8i+, can handle a
phenomenal transaction level. I've worked with sites
that replicate 20GB+ a day and db performance is
excellent. On the other hand, I've also worked with
sites that were such a mess that replicating 100MB a
day was an effort.
I think there's just less margin for error in
designing and configuring a replication environment
when you're dealing with that high a transaction load.
