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

Description

Why does modern software feel so slow? Casey Muratori joins Marco to talk about performance-aware programming, the infamous Windows Terminal story, expectations in game servers, AI hype, and why Python might just be holding us all back. A deep, unfiltered conversation about performance, software culture, and the future of programming. What you’ll learn: – The truth about software performance (and how to avoid “ridiculously slow” code) – Behind the scenes of the Windows Terminal controversy – Performance myths: Java vs. C vs. Assembly – How many players can a game server really handle – The “excuse parade” developers use when things are slow – AI: Productivity boost or theft? Casey’s take – Should companies rewrite bloated software? – Why Casey would get rid of Python #TheMarcoShow #Developers #Performance #AI #CaseyMuratori ⏱️ Timestamps: 00:00 Teaser 01:00 Meet Casey Muratori 04:00 The Windows Terminal story 15:00 The “excuse parade” of slow software 18:30 Game servers and performance expectations 24:00 The billion-row Java challenge 46:00 Getting 30x performance gains 52:00 Modern CPUs and performance myths 1:09:00 Should companies rewrite bloated software? 1:18:00 Casey’s take on AI 1:33:00 AI and ethics: who owns the data? 1:40:00 Rapid-fire questions: OS, IDEs, languages 1:50:00 Giveaway and Outro Useful materials mentioned: Casey’s Performance-Aware Programming Course: https://www.computerenhance.com Follow Casey Muratori: X: https://twitter.com/cmuratori Follow The Marco Show: Instagram: https://instagram.com/themarco.show TikTok: https://tiktok.com/@themarco.show _______________ The Marco Show is a bi-weekly podcast about coding, developer tools, and, of course, AI.
