Question

我对应用程序的响应时间有一些抱怨，所以我正在研究哪些方面可以加快速度。使用分析阶段监听器和一些分析包装器，我希望找到一些需要缓存的东西。然而，情况似乎并非如此。典型的示例运行看起来像这样：

Controller>afterRestoreView completed in 0:00.000.044769
PhaseProfiler>LIFECYCLE>RESTORE_VIEW completed in 0:00.017.090231
PhaseProfiler>LIFECYCLE>APPLY_REQUEST_VALUES completed in 0:00.012.076884
PhaseProfiler>LIFECYCLE>PROCESS_VALIDATIONS completed in 0:00.003.804324
PhaseProfiler>LIFECYCLE>UPDATE_MODEL_VALUES completed in 0:00.002.898762
PhaseProfiler>LIFECYCLE>INVOKE_APPLICATION completed in 0:00.000.113143
Controller>beforeRenderResponse completed in 0:00.000.012222
Controller>afterRenderResponse completed in 0:00.000.003143

因此RenderResponse中的内容大约需要2.9秒，但它不是我的事件处理程序，它不是我的变量绑定。使用System.nanoTime并不是完全相同的，但与System.currentTimeMillis相比，它似乎增加了大约一秒或更少，所以我仍然缺少相当多的时间。我只能占不到21毫秒。

是否有深入挖掘的技术？

虽然我无法让代理在R9上运行，但它的CPU分析器做得很好。它可以查明特定SSJS，Java方法或Notes API调用的瓶颈。强烈推荐。

做一些性能调整，不知道如何找到时间花在哪里
