Save my name, email, and website in this browser for the next time I comment. If it's mostly just this one piece of code that causes the problem, you can spin up several child processes (perhaps as many as the number of CPUs you have in your server) and then feed them the CPU-intensive work and leave your main node.js process free to handle incoming (non-CPU-intensive) requests with very low latency. Thanks for contributing an answer to Stack Overflow!
