Slow response with WSO2 enterprise integration using message broker

Question

I use WSO2 EI 6.1.0 to this scenario:

1. A client(SOAPUI project) send a message to a proxy service(PS_A) inside EI.

2. The proxy service(PS_A) store the message in a Queue, define in embebed MB, with a response queue defined with transport.jms.ReplyDestination.

3. Another proxy(PS_B) get the message from the queue and send a message to a backend service, with the backend response, create a new message and send it as a response.

4. The response arrive to the client.

My problem it´s that the response time is very slow, about 9s with the embebed MB. If I use a external broker like ActiveMQ, the response time it´s about 400ms or less.

Answer 1

The WSO2 MB has various settings / parameters that you can configure such in axis2.xml file or inside the proxies (Producer - PS-A) and (Consumer - PS-B). Therefore, to make the execution process faster, you can use the caching level, such as for producer and consumer.

Ps_A: < parameter name="transport.jms.CacheLevel">producer< /parameter > Ps_B: < parameter name="transport.jms.CacheLevel">consumer< /parameter>

Hope this helps
