Do you have the methodology and data that you used to obtain this figure? Because to be honest I'm quite dubious, especially for an app which is CPU bound.
- dmitrim 9y agoWe are measuring both, individual profiler overhead when active (printed by the agent in debug mode) and total CPU and memory overhead of the app running over long periods of time with and without agent.
- orf 9y agoAre these apps under load? Is there really only a 1% difference when running apache-bench or seige on the applications?
- dmitrim 9y agoYes, the apps were under simulated CPU load, memory allocations, etc. The good thing with sampling profilers is that overhead stays relatively stable even under high load.
