用于 Firefox 的 Javascript 内存分析器 [英] Javascript memory profiler for Firefox

问题描述

是否有用于 Firefox 的工具/插件/功能可以转储您在页面/脚本中创建的 Javascript 对象的内存使用情况?我知道 Firebug 的分析器，但我想要的不仅仅是几次.类似于 Yourkit 用于内存使用的 Java 分析的东西.

Is there a tool/plugin/function for Firefox that'll dump out a memory usage of Javascript objects that you create in a page/script? I know about Firebug's profiler but I'd like something more than just times. Something akin to what Yourkit has for Java profiling of memory usage.

原因是一位同事在数组中使用 id 作为键"，并在他这样做时创建了 1000 个空槽.他认为这是无害的，而我的意见不同.我想提供一些证据来证明我是否正确.

Reason is that a co-worker is using id's for "keys" in an array and is creating 1000's of empty slots when he does this. He's of the opinion that this is harmless whereas my opinion differs. I'd like to offer some proof to prove whether I'm right or not.

推荐答案

我还没有尝试过软件验证工具，但 Mozilla 有一些工具可以跟踪 firefox 消耗的整体内存以阻止泄漏:

I haven't tried the Sofware verify tools, but Mozilla has tools that track overall memory consumed by firefox for the purpose of stemming leaks:

还有这个家伙说在闭包的上下文中避免使用大数组，朝向文章底部

There's also this guy saying to avoid large arrays in the context of closures, towards article bottom
