Been playing with Python Flask writing some backend REST API for our game backend.
Trying to work on deploying the API using Gunicorn using gevent

sudo apt-get install libevent-1.4-2
sudo apt-get install libevent-dev

easy_install greenlet
easy_install gevent

My Gunicorn config file:

$ cat gunicorn.py 

import os

def numCPUs():
    if not hasattr(os, "sysconf"):
        raise RuntimeError("No sysconf detected.")
    return os.sysconf("SC_NPROCESSORS_ONLN")

bind = "0.0.0.0:8000"
workers = numCPUs() * 2 + 1
backlog = 2048
#worker_class ="sync"
worker_class =  "gevent" 
debug = True
daemon = True
pidfile ="/tmp/gunicorn.pid"
logfile ="/tmp/gunicorn.log"

Running the Flask Application:

$ gunicorn -c gunicorn.py mp:app 

$ tail /tmp/gunicorn.log

2011-04-19 10:33:40 [1597] [INFO] Booting worker with pid: 1597

Woops.. seems working.
Time to run load testing with ab and siege.
