PATCH: couch_stats_aggregator should use queue instead of list
--------------------------------------------------------------
Key: COUCHDB-797
URL: https://issues.apache.org/jira/browse/COUCHDB-797
Project: CouchDB
Issue Type: Improvement
Components: Database Core
Reporter: Sean Bartell
Priority: Minor
Attachments: 0001-stats-use-queue-instead-of-list-for-speed.patch
couch_stats_aggregator uses a list to store samples, but many times per second
adds a value to the front or removes one from the end. This patch makes it use
a queue instead. Statistics take up little CPU time, but there's a noticeable
improvement when CouchDB is idle.
