Okay, if you uncomment line 26 in /etc/couchdb/default.ini:
http://bazaar.launchpad.net/~wibblymat/ubuntu/oneiric/couchdb/update-
to-1.1.0/view/head:/etc/couchdb/default.ini.tpl.in#L26
socket_options = [{recbuf, 262144}, {sndbuf, 262144}, {nodelay, true}]
Then the performance is back up to what is was in 1.0.1. I guess
CouchDB was perhaps running with nodelay by default before, and now it
isn't? Anyway, gory benchmark details running with that line
uncommented:
