haystack: FARMReader slow

Question I am running one of the samples in K8 pod (gpu) It get stuck in FARMReader for long (30+ mins) and time out. Any reason? All i added was 2 .txt document

    reader = FARMReader(model_name_or_path="deepset/roberta-base-squad2",
                            use_gpu=True, return_no_answer=True, no_ans_boost=0.7, context_window_size=200)

    retriever = ElasticsearchRetriever(document_store= document_store)
     
    pipe = ExtractiveQAPipeline(reader, retriever)
    
    # predict n answers
     prediction = pipe.run(query=question, top_k_retriever=10, top_k_reader=3)
