LOGGED INFORMATION To: "user@couchdb.apache.org" , Scott Weber Cc: "replication@couchdb.apache.org" Content-Type: text/plain; charset=ISO-8859-1 X-Virus-Checked: Checked by ClamAV on apache.org 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 test: {"from":"http://127.0.0.1:5984/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!).
