Hello Joshi What is the volume involved when you say slow. I have been working with Adv.Replication and i can vouch for it. What platform? How many master's involved? If you search for streams in this forum few months ago, you will find there was a bug with Streams where in it could not catch up with when the volume/log switching was pretty high and was found to be a bug. I have worked extensively but i would say Streams is much easier to set up and get started. It mines the logs unlike Replication.
