I want to use chrome debugger for JavaScript performance.
I use the chrome debugger
to record the JavaScript CPU profile
.
Then, I got the record graph below:
And each function will show me the detail about cost time, like that:
My questions are:
Q1: what is the mean of Self Time and Total time?
Q2: Why the count of Self time is not equal to Total time?
Q3:If I want to improve the perf about this code, may I just need to care about highly Self time function?
BTW, this question is not same for mine. Because, I have Q3 and that question is choose the heavy model to see the CPU profile but I choose the chart. So I want to know whether they are the same mean?
