&lt;p&gt;本来想直接写理论、和实践分析的，但为了不 “赶客出門” 和不 TL;DR，还是以故事形式展开吧。语言要生动活泼。&lt;/p&gt;
&lt;h2 id=&#34;故事的开始&#34;&gt;故事的开始&lt;/h2&gt;
&lt;p&gt;话说，一次性能测试中，TPS 死活压不上，应用的响应时间增加。根据 Brendan Gregg 大神的最高指导精神，我开始用 &lt;a href=&#34;https://www.brendangregg.com/usemethod.html&#34;&gt;USE(Utilization Saturation and Errors)&lt;/a&gt; 方法学去定位这个性能问题。&lt;/p&gt;</description>
