測試峯值結果

我正在運行測試，其中250個併發呼叫被不斷地從JMeter的3.1發送到我的騾子應用程序的工作流程和結果都開始了良好的效果，但突然開始飆升，從20毫秒到6秒以上。測試峯值結果

我已閱讀此文檔：https://docs.mulesoft.com/mule-user-guide/v/3.8/tuning-performance並嘗試將Max Active Threads從默認的16位更改爲300，因此每個事務都將擁有自己的線程，但仍會出現尖峯。

我已經創建了具有HTTP監聽器，並且將有效負載的200個項目和一個JSON陣列的集有效載荷分量的測試流程再次結果是良好的開始，但然後啓動尖峯。

還有什麼我可以看看，可能會導致尖峯？

我使用Anypoint工作室6.1和Mule 3.8.1和使用Apache JMeter的3.1測試。

摘要結果：

下面是結果測試XML的總結它是始終在兩位數前突然採取了幾乎3倍的時間纔再次回到正常完成請求（這發生在在多個場合，因爲它經過的調用）

你是如何內構建JSONArray的原因HTTP採樣器？請你可以發佈你的測試計劃的樹結構，並且你的代碼是用來存儲JSONObject的嗎？ – Selva

增加JMeter的文件，並剪斷結果彙總，XML測試流程和HTTP連接器配置 – user3165854

我同意以下迪米特里的答案。由於您在同一臺計算機上運行測試，因此可能會遇到資源問題。鑑於已用時間與{連接+延遲}之間的巨大差異，這表明您在連接到locahost時遇到了問題。 – Selva

展望Connect和Latency度量標準，高響應時間與高連接和延遲相關，所以我的期望是由於網絡問題，您得到了這些「尖峯」。
