JPDA MethodEntryEvent makes the application run very slowly

Question

I am trying to capture all the method calls made in any android application. For this, I use JDI to register MethodEntryRequest for each running application thread. I will be able to do this, but I ran into a problem that the application is getting very slow. So I want to know that I am doing something wrong in my implementation. I add my code where I first register a ClassPreparedRequest to catch the loading of each class by the application, and in this I register a MethodEntryRequest with threadfilter for the thread, which causes the class to load.

 if(!traceMap.keySet().contains(event.thread()))
    {
        EventRequestManager mgr = vm.eventRequestManager();
        MethodEntryRequest menr = mgr.createMethodEntryRequest();
        menr.setSuspendPolicy(EventRequest.SUSPEND_NONE);
        menr.addThreadFilter(event.thread());
        menr.enable();
    }

ClassPreparedRequest Registration Code

    ClassPrepareRequest cpr = mgr.createClassPrepareRequest();        
    cpr.addClassFilter("com.example.*");
    cpr.setSuspendPolicy(EventRequest.SUSPEND_NONE);
    cpr.enable();
