Betreff: [Twisted-Python] Speed of twisted on Amazon EC2<br>
<div><div class="h5"><br>
Hi all<br>
I recently wrote a hello world HTTP app in Twisted, Cyclone, node, Go and Scala on the Play framework, and used a combination of ab and gattling to see how fast each was on an m1.small instance on Amazon EC2. I also tested it on bare metal (my laptop:)) but I'll get to that later.<br>
The code I used for twisted was the web server code sample from the front page of <a href="http://twistedmatrix.com" target="_blank">twistedmatrix.com</a> with the numberRequests increment dropped and a simple "Hello World!" returned instead.<br>
For cyclone I used the sample code from the cyclone docs with the same string being returned.<br>
Node was the sample from their front page.<br>
Play and Go I've never worked with before so those were copy pastes from various examples on their pages but again same URI and return string as the other frameworks.<br>
