erlang: 5.8.5
spidermonkey: 1.9.1.15-2ppa0+1

siege -c 80 -i -d 1 URL
Typical response:

Trying with 20-40 concurrent users is fine.
Tweaks: I've tried everything listed in this document:
http://wiki.apache.org/couchdb/Performance
Using htop I can see the memory usage slowly climb before couchdb crashes.
Usually around 3000 available of 14980MB available.
Thanks
