<p class="wp-block-paragraph">你开了二十来个标签页，切换开始卡半秒，打开系统任务管理器一看——一排一模一样的&#8221;Google Chrome&#8221;进程，谁也认不出是谁。MakeUseOf 撰稿人 Robin John 以前只能随手关几个标签碰运气，直到发现浏览器自带一个任务管理器，每一项都标了名字。</p>

<p class="wp-block-paragraph"><strong>快捷键是 Shift + Esc</strong>（Chrome 在当前窗口时按）。被别的软件占用了的话，从右上角三个点 → 更多工具也能打开，Mac 上在&#8221;窗口&#8221;菜单下。它显示的是网页真实标题和扩展真实名称，右边跟着内存数字，点&#8221;内存占用量&#8221;这一列排序，几秒钟就知道谁最能吃。</p>



<p class="wp-block-paragraph"><strong>真正的意外通常是扩展。</strong> Robin John 排序后发现，一个密码管理器、一个语法检查器加一个广告拦截器，三个加起来比他实际打开的十个网页还多。扩展整个会话期间一直在跑，有些还往每个页面注入脚本——标签页越多开销越大，列表里却只占一行。</p>



<p class="wp-block-paragraph">右键点表头可以再加两列：<strong>JavaScript 内存</strong>能看出哪个网页应用自己在堆里屯东西，<strong>空闲唤醒次数</strong>对笔记本尤其有用，某个进程在后台不停唤醒，内存看着正常，电量照样掉。设一次 Chrome 就记住了。</p>



<p class="wp-block-paragraph">选中一行点&#8221;结束进程&#8221;，只干掉那一个标签或扩展，标签还留在栏上显示错误页，刷新就回来。某个页面卡死时，这比整个浏览器强退划算得多。</p>



<p class="wp-block-paragraph">注意这里的数字一直在动，同一标签隔三十秒读数就不同，也和系统显示的总占用对不上。它擅长揪异常值，不适合精确测量。</p>



<p class="wp-block-paragraph">我的判断是，它真正的价值是把&#8221;关标签页&#8221;从玄学变成有据可依。视频站排在前面很正常，但一篇两小时前打开、你早忘了的新闻页，数字还在往上爬，那多半是内存泄漏。</p>
