Subject Re: Replication of attachment is extremely slow.. LOGGED INFORMATION

The important thing to note here is that test 1 is using URLs for
databases where tests 2 and 3 are using internal replication. Reading
the logs it shows that the request to write the attachment took about
72 seconds. Out of curiosity could you rerun test 3 twice more with
the following JSON bodies:

{"from":"http://localhost:5984/from", "to":"to"}
{"from":"from", "to":"http://localhost:5984/to"}

This should narrow down if there's a problem with reading attachments,
writing attachments, or some weird interplay between reading and
writing attachments.

If it turns out that the only slow version is when both are using the
"http://localhost:5984/dbname" versions then can you run one more

{"from":"", "to":"http://localhost:5984/to"}

If that's also slow then we probably have a weird problem with the
multipart code (fun!). If its not slow then most likely this is a bug
in the HTTP worker pool implementation (also fun!).
