Subject [jira] [Updated] (COUCHDB-1214) Weird replication: ~12k design document takes almost twice as long as ~7MB other documents to replicate
Date Thu, 07 Jul 2011 13:38:16 GMT

     [ https://issues.apache.org/jira/browse/COUCHDB-1214?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jürgen Lorenz Simon updated COUCHDB-1214:
-----------------------------------------

    Description: 
The replication is filtered in each case. The design document in question is about 12k big,
the overall size of the DB (disk_size) is about 6.8MB. The replication of nothing but the
design document takes about 48 Seconds, the replication of the entire rest 28 Seconds. 

The two filters used look like this:

designs: "function( doc, req ) { return doc._id.search(/_design/) >= 0; }"
attachments: "function( doc, req ) { if (doc.docType == "attachment" || doc.docType == "article"
|| doc._deleted) { return true; } }"


The version in the ticket was the server couch (source). The target couchdbs executing the
pull-replication were 1.1.1 and 1.0.2 (same result) running on various hardware (Dell Laptop
or iMac).
