High CPU overhead while using spring-cloud-gateway with agent

[123liuziming]

I am evaluating the performance impact of otel java agent on spring-cloud-gateway application, and I found the performance overhead introduced by agent in this scenario to be very high.


CPU usage doubled in my performance test scenario(I do the performance test with&without otel java agent, and send requests to a spring-cloud-gateway application with 1000 QPS).

I 've analyzed the flame graph

The main reason for this performance overhead is because agent use resetOnEachOperator to propagate context on all the operators. But in this scenario, most of the context propagations are useless for users because SCG do not produce any span in those operators. Do we have some ways to avoid those context propagation?
