Concurrent, non-blocking, JIT, VM for running JavaScript as a scripting language on a server. The non-blocking event based IO on one thread drastically reduces memory overhead which increases speed allowing massive throughput. A simple "hello world" web server on NodeJS has been nearly 6 times faster than Apache on the same hardware... and that's comparing a script, with compiled code.
Google Coder Web Development uses a Raspberry Pi as the web server, and development environment.
Also: On the Microsoft IIS platform: Javascript in ASP, Jscript in ASP is faster than VBScript

npm install -g autocannon npm install -g clinicAutocannon generates sample requests. e.g. autocannon -c100 url will generate 100 concurrent random requests. Clinic clinic doctor --on-port='autocannon -c100 url' -- node index.js opens an HTML file with all sorts of profile data. clinic flame --on-port='autocannon -c100 url' -- node index.js generates a flame graph, which you can drill down into in order to find the slow parts of a script.+
Note that this does NOT mean NodeJS can't take advantage of multiple processors or multi-threaded work:
Use cluster when you want to parallelize the SAME flow of execution and server listening.
http://nodejs.org/api/cluster.htmlUse child_process when you want DIFFERENT flows of execution working together
http://nodejs.org/api/child_process.html
and take advantage of built in Inter-Process Communication to pass objects between the processes.
