- 4Hacker News·7/13/2026researchUsing a branchy "useless" if to speed up a loop
The post describes a micro-optimization for a compressor’s path-reconstruction loop, where a dependent memory access limits performance. By adding a branch that usually predicts the common case, the author aims to let the CPU speculate more effectively and reduce loop latency. The article argues that an apparently useless conditional can improve throughput when the branch is rarely taken.
