Re: Recommendation for small, fast, Python based web server
Hello, I've looked at the web servers that come bundled with the Python standard library[1] and they are too slow. Apparently you have debugged your speed issue so I suppose you don't have performance problems anymore. Do note, however, that Python is generally not as fast as C -- especially for low-level stuff -- and a Python Web server will probably serve around 10x less requests per second than a C Web server like Apache (this will still give you hundreds of simple requests per second on a modern machine). In any case, as far as functionality, robustness, portability and community support are concerned, you probably can't go wrong with Twisted.

I don't think that number is fair for Python. I think a well written Python web server can perform in the same ballpark as most mainstream web servers written in C. Especially Apache, which really isn't a top performer. And I'm pretty sure a well written Python server can outperform a badly written C based server easily. -irmen -- http://mail.python.org/mailman/listinfo/python-list

You are under-estimating how much of an impact Python's interpretation speed has on low-level code.

Or they might be based on a polling model? I'm not sure what caused the slowness you've experienced -- using Python in a CGI environment requires starting the Python interpreter each time. However if the interpreter starts just once, I've not had notable performance issues for low-volume sites (using the BaseHTTP builtin). For higher-volume sites, you might reach for Twisted which WebStack supports as well. I believe both WebStack and Twisted are redistribtable as needed. -tkc [1] http://www.boddie.org.uk/python/WebStack.html -- http://mail.python.org/mailman/listinfo/python-list
Re: Recommendation for small, fast, Python based web server
I'm looking for a small, simple, fast, Python based web server for a simple, client side application we're building. We don't want to distrubute and support a real web server like Apache or Tomcat or depend on the presence of local web server such as IIS. The application in question will service AJAX requests from a browser. We're not looking for a web framework like Django, Plone, etc. I've looked at the web servers that come bundled with the Python standard library[1] and they are too slow. I suspect this is because they don't maintain a session between the client and server, thus every GET/POST request repeats the session setup and break down process. Or they might be based on a polling model? Here are the other Python based web server implementations I'm aware of: - cherrypy - web.py - twisted Any recommendations appreciated (Python 2.6 preferred but open to Python 3.1 options). I'm using cherrypy for this purpose, actually together with turbogears 1.

Tim, I've used WebStack[1] for this in the past. It allows for stand-alone serving as well as plugging nicely into various real servers (apache+mod_python, etc) with a small tweak in how it's configured. Thanks for that recommendation. I'm not sure what caused the slowness you've experienced (... with running local versions of Python web servers) Thanks to a past post by Christoph Zwerschke c...@online.de, I was able to identify the problem. Windows (XP, Vista, Windows 7) tries to do a IPV6 connection which times out after a second followed by an IPV4 connection which is almost instantaneous. Apparently this is a known problem that is a Windows issue [1] - not a Python problem. Two workarounds: 1. Use 127.0.0.1 as your URL vs. localhost -OR- 2. Edit your Windows hosts file (c:\windows\system32\drivers\etc\hosts) and create a virtual domain name, eg. put the following on a line by itself: 127.0.0.1 mydomain.someext And then use mydomain.someext vs. localhost Note: Editing your hosts file requires admin rights under Vista and Windows 7.

Daniel, I'm using cherrypy for this purpose, actually together with turbogears 1. My research has constantly pointed back to cherrypy as a tool of choice for building local web servers. My initial impression was that cherrypy was too big and complicated for my simple task. However, I'm going to re-examine this assumption and take another look at cherrypy. Thanks for your help!
