Timers

Timers is a simple framework for accumulating timing data in applications in a hierarchical way to keep track of how much time gets spent in various parts of the code.

How to use this in practice:

allTimers := New()
t = allTimers
t = t.Start("foo")
foo()
t = t.Handover("bar")
bar(t)
t = t.Stop()
func bar(t timers.Timer) {
     t = t.Start("a")
     a()
     t = t.Handover("b")
     b()
}

This will create a structue with timers as: foo bar bar.a bar.b

You can then use Foreach to collect the data from the timers.

Allocating the timer with NewMemStats() will also record some memory usage statistics along with timing data, but keep in mind that this makes the timers a magnitude slower.
