Java auto instrumentation caused latency in REST API calls. How to see the split up of these latency

[jaisonsteephen]

Hi, When we analyzed our business api call (which is just calling Get service call UI-->ServiceA-->ServiceB-->ServiceC) with opentelemetry, we found there is some additional latency introduced. We called 10,000 such request using Jmeter, and found the average response time

Following is the configuration. Similar configuration we applied to all three of our services

• with opentelemetry agent is 21.73 ms
  Configuration: java -javaagent:opentelemetry-javaagent-all.jar -Dotel.resource.attributes=service.name=java-service1 -Dotel.traces.exporter=jaeger -Dotel.propagators=b3 -Dotel.exporter.jaeger.endpoint=http://ip*****:port**"
  Dotel.metrics.exporter=none -jar application.jar

• without opentelemetry agent is 17.24ms
  Configuration: java -jar application.jar

How we can get a split up of these latency, to understand who is causing this latency within opentelemetry agent & how we can fine tune it
