I did a very non-scientific study of the amount of time programmers actually spend writing code. OK, I just typed “How much of a software developer’s time is spent coding” into the search bar and looked at the top few articles, which gave percentages ranging from 10% to 40%. How much time and effort does that save?

What these steps have in common is that monitoring tools are not in sync with new changes in code or topology and this observability data is often siloed within different tools and teams. This approach was presented virtually in the on-demand observability clinic, Getting Started with Observability-Driven DevOps and SRE Automation.

While Federico definitely has good points there, there is some truth in these myths too.

47.418 MB is a pretty tiny amount and should take less than 10 ms to fault in (see Hidden Costs of Memory Allocation for details), and there were no new allocations during the trace, so the KiPageFault overhead was definitely excessive.
