    Wildfly 9.0.0CR1 memory needs...

    tdanecito

      Hi,

      I am running 4 restful (JAX-RS) web services in Wildfly 9.0.0 CR1 and I was wondering what is the minimum recommend memory needs for Standalone mode for Wildfly itself?

      The restful web services are stateless and need very little memory probably less than 10MB. For Tomcat it used to be recommended to have 200MB for that. I am hoping I do not need more than 100MB for Wildfly.

       

      Thanks!

          Run a load test, figure out what your live set size is, multiply by four. Run the load test again and check if your gc latencies are OK.

            Sorry I tried to make the question clear. After installing Wildfly 9.0.0.CR1 WITHOUT ADDING ANY APPLICATIONS what is the memory that is needed for Wildfly itself? Whan Red Hat says it is lightweight I expect memory needs for Wildfly itself to be low to start with. So what is the memory needs then? Does not Red Hat know??

             

            Thanks,

              about 7-12MB heap is used by empty wildfly instance.

                Many thanks Tomaz! I passed that along to the middleware group.

                Is there a GA release date for Wildfly 9.0 publicized anywhere? Seems like Red Hat is close to releasing it.

                  It's my understanding that WildFly is not a Red Hat product and not supported by Red Hat. It's a community project and supported by the community. JBoss EAP is a Red Hat product and supported by Red Hat.

                    Indeed, WildFly is community driven.
