I'm not sure how to answer this question as the GODEBUG logs generally don't include any time markings anyhow. When they do include time, the time should be accurate and precise. > 3) Right now, i am trying to understand the runtime especially the relation > between G,M and P.

The GODEBUG logs aren't really intended for that, although you will something from GODEBUG=schedtrace=1. I'm not sure what knowledge you are starting from.
