Google Coder Web Development uses a Raspberry Pi as the web server, and development environment.
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.
Use child_process when you want DIFFERENT flows of execution working together
and take advantage of built in Inter-Process Communication to pass objects between the processes.
