Look in:

org.rhq.enterprise.gui.coregui.client.gwt.GWTServiceLookup.SessionRpcRequestBuilder.doCreate(String)

See this code:

   // TODO Don't use the expensive determineName except in dev mode
   rb.setCallback(new MonitoringRequestCallback(determineName(), rb.getCallback()));

Notice the TODO and look particularly the impl of determineName:

        public String determineName() {
            Exception e = new Exception();

            StackTraceElement[] stack = e.getStackTrace();
            // Skip the first two stack elements to get to the proxy calling
            for (int i = 2; i < stack.length; i++) {
                StackTraceElement ste = stack[i];
                // e.g. "org.rhq.enterprise.gui.coregui.client.gwt.ResourceGWTService_Proxy.findResourcesByCriteria(ResourceGWTService_Proxy.java:36)"
                if (ste.getClassName().startsWith("org.rhq.enterprise.gui.coregui.client.gwt")) {
                    return ste.getClassName().substring(ste.getClassName().lastIndexOf(".") + 1) + "."
                        + ste.getMethodName();
                }
            }
            return "unknown";
        }

This has to be expensive. We should implement the TODO at minimum (or just take out the getDetermineName's processing of the stack trace).

I don't know what the request "name" is for - but I suspect its just for logging purposes.
