On a new Linux installation I compared branch 1.1.x against branch 1.0.x - = only set the nodelay option for 1.1.x, as Beno=C3=AEt found recently that u= nder Linux it has a significant positive impact - https://github.com/benoit= c/restkit/issues#issue/5 I made a 200 seconds relaximation read and writes test with documents of ~4= kb and here are the results: http://graphs.mikeal.couchone.com/#/graph/698bf36b6c64dbd19aa2bef63404ecbc These results match yours - 1.1.x has about the same performance as 1.0.x (= reads seem slightly better in 1.1.x) Closing this ticket > branch 1.1.x with worse database read/write performance > ------------------------------------------------------- > > Key: COUCHDB-1013 > URL: https://issues.apache.org/jira/browse/COUCHDB-1013 > Project: CouchDB > Issue Type: Bug > Reporter: Filipe Manana > Fix For: 1.1, 1.2 > > > The issue is described in an e-mail sent to the development mailing list: > http://mail-archives.apache.org/mod_mbox/couchdb-dev/201012.mbox/%3CAANLk= Tim5uNVkSCVhHuu_1GA1xKVFJFBWE2-Wtb4vVx8g@mail.gmail.com%3E > It also affects trunk. > Would love to have results from other on Linux/ext4, and other OSes/files= ystems besides Mac OS X. -- This message is automatically generated by JIRA.
