Dave Cottlehuber commented on COUCHDB-1874:

To be confirmed, but seems plausible.

you see the same slowdown if you omit that flag?

but I don't remember the history of the codebase well enough to say whether the bug might
be latent in Apache CouchDB.

> bq. You're right: When disabling "continuous", replication seems more stable and efficient
(1200 doc/sec). Thank you !

gradually fills the mailbox, which sounds like it ought to affect couchdb.
