I don't know, and if anybody does know, they haven't said. But a Pylons request would run inside a tread / greenlet / process / async-thing. So you can make a HTTP server that spawns worker greenlets instead of threads. Maybe PasteHTTPServer can be subclassed for this. Then, if you get it working, you can make an entry point so it can be loaded from the INI file.
There may possibly be issues with StackedObjectProxy (the Pylons special globals) and SQLAlchemy's scoped_session, but Ben or Ian or Mike Bayer could answer that better than I can. --Mike On Wed, Jan 13, 2010 at 12:36 PM, jgard...@jonathangardner.net <jgard...@jonathangardner.net> wrote: > What about Python greenlets to handle concurrency? > > http://pypi.python.org/pypi/greenlet > > Basically, it's Stackless in CPython as a module import. > > On Dec 16 2009, 4:10 pm, Joan Miller <pelok...@gmail.com> wrote: >> I've to starting to play with Go to manage the concurrency and it's >> awesome. >> >> On 16 dic, 23:51, Damjan <gdam...@gmail.com> wrote: >> >> > > One other issue is that the thread overhead is not usually the >> > > bottleneck in a WSGI application.
