It's backwards. HTTP is the weaker of the two transports, though tried and true. Mongrel2 can used to proxy HTTP to ZMQ nicely. Check these slides for an overview of all the things ZMQ can do: http://j2labs.tumblr.com/post/5036176531/zerom

I don't like the idea of everything using HTTP. I prefer ZMQ. There is a substantial work done to process all the HTTP overhead. In addition to that there is no load-balancing included and it would likely be delegated to a whole new service

This test is for a pointlessly weak concurrency level of 25. Under serious load the difference is much more gigantic showing that Twisted can't handle the same load as gevent.

Will be awesome to see more of what we get from pypy. Eventlet will probably gain a lot too, for those with a taste for the implicit eventloop.

Updated: https://gist.github.com/882555 - Same URL as on http://brubeck.io/readme.html , but with new data I just finished collecting.

I see. I will update. This test was also performed with Eventlet and I found Eventlet to occasionally fail requests. I have since switched over to Gevent and the performance is significantly better than Tornado now. I will update this test

As the initial author of Brubeck, I'm very glad to hear this!

There are very few Tornado compatible async drivers, so I don't believe it is a simplification.

Try Brubeck. It's a Python web framework built around Gevent, DictShield and ZeroMQ. It communicates with Mongrel2, it's web server, via ZeroMQ sockets so even the annoying design of WSGI is moved out of the way. It converts your blocking c

Don't use Tornado unless you plan to build a full SOA. Python drivers are blocking by default and Tornado offers no support for that, meaning Tornado blocks if you have database calls in your code. Use gevent. Huge community. Simply works a

I know the rage is async & nonblocking, but putting Python behind Apache is a good way to get predictable performance without concerns for calls that block, since they're mitigated via threads. Also, it helps to have money since this ap

You, my friend, have made excellent points and I yield to you now. I hope this conversation is informative for readers.

That's entirely dependent on what the work being done is. It's typical for gevent users to use the built-in queue systems to pass messages between coroutines, similar to Erlang's actor model. I do t believe a lot of work would be required i

Gevent wasn't designed for multicore because it doesn't exist today. It's fair to assume some work would have to be done to continue using it safely. Edit: Solve the problems you actually have.

> The weakness of callbacks is the lack of multicore support. You suggest that gevent won't work in preemptive environment if it wants to support multiple cores, alas I'm still not convinced as to why. The greenlets are cooperatively sc

This link is flawed. It points towards eventlet but gevent is significantly better. Not sure why Ted felt otherwise, but I speculate that it's because at the time of writing gevent was considered incomplete compared to eventlet. To be clear

Or just use gevent or eventlet. It's not necessary to use a whole different branch of python. On top of that, gevent outperforms both twisted and tornado because the eventloop is libev, meaning it's written in C instead of pure python.

Very clever move to let his clients know they should keep tabs on him. It advertises his integrity and informs people he's leaving.
