Summary: Improve couch_lru performance
Key: COUCHDB-3191
URL: https://issues.apache.org/jira/browse/COUCHDB-3191
Project: CouchDB
Issue Type: Improvement
Components: Database Core
Reporter: Paul Joseph Davis
This ticket is to track work around updating couch_lru to be more performant.
So far I have a change that replaces the gb_tree/dict pair with two khash'es.
This approach allows us to change the algorithmic speed from O(N log N) to O(1)
which should in theory make this faster.
This is motivated by the poor behavior of couch_server when under load by lots
of concurrent clients and a high max_dbs_open value.
