Re: [go-nuts] Re: What is pprof overhead like when gathering a profile?

What we do is to periodically turn on profiling for X seconds, collect some data and turn it off again. We do it at every once a while periodically. We target a single or a group of instances in a large group. On Mon, Jul 24, 2017 at 6:11 PM, Dave Cheney wrote: > Another option
