My first tests for Centos were against erlang R12B, I'm seeing yet 
another speed improvement using R14B04 on Centos 6.

{"couchdb":"Welcome","version":"1.2.0"}

real    4m45.824s
user    0m0.003s
sys     0m0.003s

Huge improvement over my current production scenario R12B, Spidermonkey 
1.7, Couchdb 1.0.2, index rebuilding takes 13m16.480s

Great job on the speed improvments!
