profiler-simulator
profiler-simulator is a program that simulates the results different profiler implementations will give for the execution of a simulated program. Currently only single threaded execution is implemented, but that should be good enough to simulate many interesting scenarios.
Below is the example output for a 100s run of a simulated program that looks like this:
func main() {
for {
workA() // 13ms
workB() // 25ms
sleep() // 62ms
}
}
Or the same program in node.js:
function main() {
workA() // 13ms
workB() // 25ms
setTimeout(main, 62) // 62ms
}
$ go run .
