FAPWS3-0.2 (WSGI server based on libev). Another strong contender for Python’s answer to Mongrel—3500 requests/s for static files, 43 for a simple dynamic (Django powered) pages and 4.8 for a heavy SQL query—all benchmarked with 300 concurrent requests.

A Fair Proxy Balancer for Nginx and Mongrel. nginx uses round robin for proxying by default; this extension module ensures requests are queued up and sent through to backend mongrel servers that aren’t currently busy. I don’t see any reason this wouldn’t work with servers other than mongrel.

A brief update with some numbers for hardware load-balanced mongrels. 4000 requests/second on 48 mongrels behind a hardware load balancer.
