J'ai fait un test de performance rudimentaire entre nodejs et IIS. IIS est environ 2,5 fois plus rapide que nodejs lors de la distribution de "hello, world!". code ci-dessous.
mon matériel: Dell Latitude E6510, Core i5 (double cœur), 8 Go de RAM, système d'exploitation Windows 7 Entreprise 64 bits
serveur de nœuds
runs at http://localhost:9090/
/// <reference path="node-vsdoc.js" />
var http = require("http");
http.createServer(function (request, response) {
response.writeHead(200, { "Content-Type": "text/html" });
response.write("<p>hello, world!</p>");
response.end();
}).listen(9090);

conclusion: IIS est plus rapide que nodejs d'environ 2,5 fois (sous Windows). C'est un test très rudimentaire, et en aucun cas concluant. Mais je pense que c'est un bon point de départ. Nodejs est probablement plus rapide sur d'autres serveurs Web, sur d'autres plates-formes, mais sur Windows, IIS est le gagnant. Les développeurs souhaitant convertir leur ASP.NET MVC en nodejs doivent faire une pause et réfléchir à deux fois avant de continuer.
Mise à jour (17/05/2012) Tomcat (sur Windows) semble battre IIS haut la main, environ 3 fois plus rapide que IIS pour fournir du HTML statique.

conclusion mise à jour: j'ai exécuté le programme de référence plusieurs fois. Tomcat semble être le serveur le plus rapide dans la distribution de HTML STATIQUE, SOUS WINDOWS.
Mise à jour (18/05/2012) Auparavant, j'avais 100 000 demandes au total avec 10 000 demandes simultanées. Je l'ai augmenté à 1 000 000 demandes totales et 100 000 demandes simultanées. IIS sort comme le vainqueur criant, avec Nodejs carénant le pire. J'ai tabularisé les résultats ci-dessous:
