Performance of Views/Lists

Hi,

I am suspecting something is wrong with my current setup. 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.

Hi Thomas,

list functions can be slow. Are views also as slow?

Cheers,
  Volker

I ran the same test on Apache CouchDB 1.1.0 built from source with
build-couchdb on Ubuntu Lucid 64 bit (High-CPU Extra Large). Performance is
slightly better but CPU is still maxed out at only 50 threads. I only get 66
requests/sec. at 750ms average response time. Feels like that's far below
what you should expect.
