Node.js性能缓慢，随机延迟峰值

我有一个node（v0.10.45）应用程序，已经运行了很长时间，没有出现问题（没有内存泄漏，代码逻辑干净）

它最近开始表现怪异，在任意位置暂停。暂停显然没有连接到任何特定的代码/数据行。因此，虽然停顿经常发生，但它们发生在不同的地方，使它们很难准确地再现

有些请求现在需要>10000ms并因此超时，即使正常响应时间是您检查了吗？该应用程序消耗约1.8GB内存，因此这可能与此相关，谢谢。node.js是否真的不能处理超过1.7GB的数据？听起来真的很悲惨。博客帖子特别有趣，也许考虑升级你的节点版本？0.10已经很旧了…实际上，0.10是升级版。到目前为止，我们一直在运行0.8，没有任何问题。您检查过吗？该应用程序消耗约1.8GB内存，因此这可能与此相关，谢谢。node.js是否真的不能处理超过1.7GB的数据？听起来真的很悲惨。博客帖子特别有趣，也许考虑升级你的节点版本？0.10已经很旧了…实际上，0.10是升级版。到目前为止，我们一直在运行0.8，没有任何问题。
