how to measure nodejs event-loop cycle time
From the question:How to detect and measure event loop blocking in node.js?
I got a scenario below,But I dont know how it can be measure the cycletime.
That looks just measure the IO cost in event-loop, since the IO queue is behind the setInterval queue.
var interval = 500;
var interval = setInterval(function() {
var last = Date.now();
setImmediate(function() {
var delta = Date.now() - last;
if (delta > blockDelta) {
report("node.eventloop_blocked", delta);
}
});
}, interval);
