Software is slow because of bad design, not slow languages
Many people are saying that AI will make software faster by rewriting it in faster languages, but this isn’t generally true. Most programs cannot be…
Quick read
An opinion piece arguing that software is usually slow due to poor design and I/O bottlenecks, not the choice of programming language. It advises using profiling and redesign (caching, async work, query fixes) rather than wholesale rewrites into faster languages to achieve meaningful speedups.
- Most real programs are I/O-bound, not CPU-bound
- Use profiling to find hotspots before rewriting code
- Optimize via caching, async jobs, parallelism, and better queries
