btw, @mixmix I did a test replication starting from you plus 2 hops which took 9 minutes, and replicated a 237 mb log. My full log is only slightly larger at 252.

I think there are two possible explainations:

1. indexes. patchcore uses several extra indexes, and flumeview-level could be faster. (also, probably the index setup could be refactored to use less indexes)
2. I'm connecting to less pubs, and am configured to only use ebt. You are probably connecting to legacy pubs, and falling back to old replication (with a tendency to download the same message twice?)

or maybe some combination of these?
