--------------------------------------------------------------
Key: COUCHDB-545
URL: https://issues.apache.org/jira/browse/COUCHDB-545
Project: CouchDB
Issue Type: Bug
Affects Versions: 0.10, 0.10.1, 0.11
Reporter: eric casteleijn
Fix For: 0.10, 0.10.1, 0.11
PUT requests to _config slow down dramatically as the size of local.ini grows.
Attached version of couch_config_writer.erl (written by Gustavo Niemeyer)
takes the write time to the config file from O(n**2) to O(n) resulting in
dramatic speedups when the size of local.ini grows to non trivial sizes.
(change from 5 minutes to 2 seconds observed on our server.)
