Hice una prueba de rendimiento rudimentaria entre nodejs e IIS. IIS es aproximadamente 2,5 veces más rápido que nodejs cuando se distribuye "¡hola, mundo!". código a continuación.
mi hardware: Dell Latitude E6510, Core i5 (doble núcleo), 8 GB de RAM, sistema operativo Windows 7 Enterprise de 64 bits
servidor de nodo
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);

conclusión: IIS es más rápido que nodejs en aproximadamente 2.5 veces (en Windows). Esta es una prueba muy rudimentaria, y de ninguna manera concluyente. Pero creo que este es un buen punto de partida. Nodejs es probablemente más rápido en otros servidores web, en otras plataformas, pero en Windows IIS es el ganador. Los desarrolladores que deseen convertir su MVC de ASP.NET a nodejs deberían detenerse y pensar dos veces antes de continuar.
Actualizado (17/05/2012) Tomcat (en Windows) parece vencer a IIS, aproximadamente 3 veces más rápido que IIS al distribuir html estático.

Conclusión actualizada: ejecuté el programa de referencia varias veces. Tomcat parece ser el servidor más rápido en distribuir HTML ESTÁTICO EN VENTANAS.
Actualizado (18/05/2012) Anteriormente tenía 100,000 solicitudes totales con 10,000 solicitudes concurrentes. Lo aumenté a 1,000,000 de solicitudes totales y 100,000 solicitudes concurrentes. IIS sale como el ganador a gritos, con Nodejs cazando lo peor. He tabulado los resultados a continuación:
