I don't want to use services like nodetime. I have small middleware nodejs application. And now I my application use cpu in strange way http://s27.postimg.org/fgzmmh85f/cpu.png So I need simple tools to profile my code. I tried to use node --prof app.js but Chrome Dev Tool doen't open generated log-file.
Please advise tool to find out bottlenecks. Also I can't understand how v8 garbidge collector works.
