     [ https://issues.apache.org/jira/browse/COUCHDB-2097?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Russell Branca resolved COUCHDB-2097.
-------------------------------------

    Resolution: Fixed

Resolving this as the performance changes are within tolerable limits. We can address specific performance issues that come up individually, but in general this looks acceptable.

> Part of one of our large enhancements required that we remove a CouchDB performance optimization on having two file handles to each .couch file. We need to make sure that this doesn't negatively impact performance.
