I am running CouchDB 1.1.2 on a High-CPU Extra Large Instance with 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each) on Ubuntu Natty 64 bit. I have 50 threads hitting a list function and only get ~45 hits/sec. with an average response time of 700ms. CPU on my CouchDB server is around 80% utilized. Thomas --00151747bb4cf5f7a904ae45c61c--
