Taking advantage of multiple cores

[Jonathan Hayward]

Will a slightly older version of Pinax, installed on top of a newer version of Django, take advantage (or be configurable to take advantage) of multiple cores?

In other words, if one request is rendering and another request comes in while the first is rendering, will Django or Pinax offload the second request to another core?

If this isn't the default, can it be enabled, and are there race conditions or other risks?

Thanks,

IMHO - Python is really the issue that keeps you from running multi-threaded effectively:

We saw big performance improvements (10-20%) by going with multiple processes instead of threading. We run Django under gunicorn with multiple processes and nginx/Apache in front for static/cached resources.

@all, thanks. Happily running with multiple processes now.
