Felix Geisendörfer	1981eee069	guide: warn about block profiler overhead (#15) ... After internal investigations, we found that poor block profiler configuration can lead to noticeable, and in some cases quite significant, overhead in production. Add a warning. I also updated the recommended rates to a 100,000,000, which is a more conservative rate and would hopefully guard against unexpected performance issues if the suggested configuration was applied to a production app. Co-authored-by: Nick Ripley <nick.ripley@datadoghq.com>	2022-02-24 16:55:50 +01:00

Nick Ripley	9137085236	guide: add note about changing mutex rate during execution (#11) ... When a mutex profile is reported, the counts and delays in the profile are scaled based on the most recently set rate. So if an application has changed its profile rate at runtime and collected different samples at different sampling rates, the samples won't be adjusted correctly when the pprof is written.	2022-01-28 14:10:39 +01:00
