Hi
We are doing some performance testing and creating worker with the following code.

 service = WorkflowServiceStubs.newInstance();
        client = WorkflowClient
            .newInstance(service,
                WorkflowClientOptions.newBuilder().setNamespace(getJiffyNamespace()).build());
        WorkerFactory factory = WorkerFactory
            .newInstance(client);
        AppProperties appProperties = SpringContext.getBean(AppProperties.class);
        Worker worker = factory.newWorker(appProperties.getWorkflowTaskQueue());
        WorkflowImplementationOptions wfio = WorkflowImplementationOptions.newBuilder()
            .setFailWorkflowExceptionTypes(Throwable.class)
            .build();
        worker.registerWorkflowImplementationTypes(wfio, JiffyWorkflowImpl.class);
        worker.registerActivitiesImplementations(
            new CallActivityAsyncImpl(client.newActivityCompletionClient()),
            new AssignActivityImpl(),
            new EvalActivityImpl());
        factory.start();

Do we need to create a pool of workers please suggest, we are creating like nearly 200 workflows per minute

No need to pool workers within a single Java process. You can run multiple Java worker processes for fault tolerance and scalability.
