We upgraded Apm agent from version 1.7.1 to 1.10. After release we discovered 100% CPU spikes on our production servers and slower performance. We removed that change and everything came back to normal. I cannot however provide any steps to reproduce, cause we cannot reproduce it locally.
Could new features in agent cause performance issues?
Do you have any test cases or load tests which check the performance?
Generally any idea how to find the cause or what could we do would be helpful.
