Ho fatto un test di prestazione rudimentale tra nodejs e IIS. IIS è circa 2,5 volte più veloce di nodejs quando viene visualizzato "ciao, mondo!". codice sotto.
il mio hardware: Dell Latitude E6510, Core i5 (dual core), 8 GB RAM, Windows 7 Enterprise 64 bit OS
server 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);

conclusione: IIS è più veloce di nodejs di circa 2,5 volte (su Windows). Questo è un test molto rudimentale e assolutamente non conclusivo. Ma credo che questo sia un buon punto di partenza. Nodejs è probabilmente più veloce su altri server Web, su altre piattaforme, ma su Windows IIS è il vincitore. Gli sviluppatori che desiderano convertire il proprio MVC ASP.NET in nodejs devono mettere in pausa e riflettere due volte prima di procedere.
Tomcat (su Windows) aggiornato (17/05/2012) sembra battere IIS a mani basse, circa 3 volte più veloce di IIS nel distribuire HTML statico.

conclusione aggiornata: ho eseguito il programma di riferimento più volte. Tomcat sembra essere il server più veloce nella distribuzione di HTML STATICO, SU WINDOWS.
Aggiornato (18/05/2012) In precedenza avevo 100.000 richieste totali con 10.000 richieste simultanee. L'ho aumentato a 1.000.000 di richieste totali e 100.000 richieste simultanee. IIS esce come il vincitore urlante, con Nodejs che fa la peggiore. Ho tabulato i seguenti risultati:
