Haha, when you said it didn't scale for multiple cores or multiple nodes, I was going to knee jerk and say, "What about Erlang!" You beat me to the punch ;) Yes, async is a technique. Just like event based programming in general is a technique. You still have to use that technique in smart ways to build big systems. >> If you're interested in doing asynchronous programming in Python but >> without the painful callback style approach used by Twisted, check out >> http://wiki.secondlife.com/wiki/Eventlet.

I haven't used Eventlet yet. It's based on the same ideas that IronPort uses, and clearly, IronPort servers are all over the world. It's nice because it "feels" like threads, but it "acts" like async. >> As usual, I recommend that anyone who wants to talk about scalability >> read "Scalable Internet Architectures".

It's a big long and boring, eh? "Scalable Internet Architectures" was a bit more to the point, and it includes a lot more stuff about scalability per se. I blogged about both of them: http://jjinux.blogspot.com/search?q=scalable+internet+architectures http://jjinux.blogspot.com/2006/11/book-review-building-scalable-web.html Happy Hacking! -jj -- I, for one, welcome our new Facebook overlords! http://jjinux.blogspot.com/ --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "pylons-discuss" group.
