find out how long require calls take in your program. this is a debugging tool for figuring out why apps load slowly
the results print the amount of time elapsed between require calls. this isn't necessarily the same as the amount of time taken by each require, but rather the time elapsed between two require calls starting (as opposed to the time taken between 1 require call starting and ending, but we can't instrument ending, only starting)
require it and make an instance
var rt = require('require-times')()
call 'start' before the requires you wanna measure
rt.start()
call 'end' when you wanna stop measuring. you should put this right after your last require() call
rt.end()
calling .end will print out the times to STDOUT, for example:
