uWSGI
In short: uWSGI is awesome. Isso has builtin support for it (and simple fallback if uWSGI is not available). Use uWSGI if you think that the builtin WSGI server is a bad choice or slow (hint: it's both).
With uWSGI, you have roughly 100% performance improvements for just using it. Instead of one thread per request, you can use multiple processes, hence it is more "web scale". Other side effects: spooling, fast inter-process caching.
Installation
You need uWSGI 1.9 or higher, fortunately you can install it with Python:
~> apt-get install build-essential python-dev
~> pip install uwsgi
Configuration
For convenience, I recommend a INI-style configuration (you can also supply everything as command-line arguments):
[uwsgi]
http = :8080
master = true
processes = 4
cache2 = name=hash,items=1024,blocksize=32
spooler = %d/mail
module = isso
virtualenv = %d
env = ISSO_SETTINGS=%d/sample.cfg
You shoud adjust processes to your CPU count. Then, save this file to a directory
if choice. Next to this file, create an empty directory called mail:
~> mkdir mail/
~> ls
uwsgi.ini mail/
Now start Isso:
~> uwsgi /path/to/uwsgi.ini
