Software Performance: Avoiding Slow Code, Myths & Sane Approaches – Casey Muratori | The Marco Show

Casey Muratori (programmer, educator, performance advocate) joins Marco to explore why modern software feels so slow, even with today’s powerful hardware. From the infamous Windows Terminal controversy to game server limits, billion-row challenges in Java, and his unfiltered take on AI. This episode dives deep into performance, programming culture, and what developers should really care about.

💡 Topics in this episode:

  • Why software performance matters (and how to avoid “ridiculously slow” code)
  • The “excuse parade” developers use when things lag
  • Expectations for game server concurrency
  • Parsing a billion rows in Java: lessons in performance
  • Containers, cloud, and performance myths
  • AI: helpful tool or unethical theft?
  • Why Casey would get rid of Python
