说明
这是2021年由Molly Rocket发布的一部课堂讲座，主题归在Software performance & optimization。它讲的是software performance这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：Casey Muratori's University of Twente guest lecture is a case study in how straightforward code can cut thousands of lines and tens of seconds of runtime down to a few dozen lines running in under a second. It uses concrete examples to show why software is often an order of magnitude slower than it should be.这些读者给出的理由，核心是：HN people recommend it to anyone wanting a practical sense of what CPUs can really do and why abstraction layers cost so much performance.讲法不绑某一条新闻，过几年仍然可以当材料看。从2021年到2025年，有6位不同的读者在6个不同月份把它推荐出来，其中明确叫别人去看的有3次。节奏接近上课，可以暂停做笔记。它假设你愿意跟着一条推导走完。如果已经会了基本定义，就把注意力放在它怎么把software performance变成能跟着复述的例子。
