Do you have some best practice how to use jersey client effectively?
In my Java EE application, I created Client -> ClientBuilder.newClient(..) as singleton with Lock.READ
I have performance issue in my microservice-oriented application. In distributed tracing, I see suspicious behaviour. Microservice A fetched some data from microservice B and it took 10 s, but from perspective of microservice B, executing took only 200ms. It seems like network problem or problem to use transport layer effectively by jersey client.
This behaviour can only see during high load. I changed singleton to stateless EJB, but no difference. I used connection - HttpPoolingConnectionManager with ApacheConnectorProvider, but also no change.
Thanks.
