Software performance & optimization Videos Recommended on Hacker News (123)
Software performance & optimization is one of the 150 topics Hacker News readers organize their video recommendations around. These 123 videos each earned real recommendations in real HN threads between 2009 and 2026 — 417 recommendations in total — and they're ranked by how many separate months the community kept coming back to them, not by view count.
Performance and optimization: profiling, benchmarks, cache efficiency, software bloat, latency, low-level optimization, SIMD, Casey Muratori, Handmade Hero, why software is slow.
Why HN keeps sending people here — on How Python was Shaped by leaky Internals, Armin Ronacher, Flask framework: “This excellent talk describes how the semantics of the "add" operation are much more complex than generally described.” — an HN commenter, 2021.
