If you’ve ever waited 12 seconds for a git clone of a 5GB monorepo behind a corporate firewall, you know the cost of poor Git server performance: $47k annual productivity loss for a 50-person engineering team, per our 2024 internal benchmark. For 15 years, I’ve tuned Git infrastructure for teams from 4-person startups to 10k+ engineer orgs, and the debate between lightweight Gitea and feature-heav
I built a Vamana-based vector search engine in C++ called sembed-engine. Recently I made a pull request that sped up queries by 16x and builds by 9x. The algorithm stayed exactly the same. The recall stayed at 1.0. The number of visited nodes did not change. The speedup came from data layout. The original code stored vectors as separate objects pointed to by shared_ptr: struct Record { int64_t
