Sustaining Git Performance Under Heavy Workloads
summary
Deploys an AI agent using Q-learning to decide lightweight repo maintenance (bitmap regeneration, repack refs, remove keep files, selective geometric repacks) and avoids full GC because of duration and cache invalidation. Agent observes bitmap index misses, loose objects/refs and search-for-objects time, trains in a high‑traffic lab with Gatling-git to compress years of activity into hours, and in experiments shrinks the search-for-objects area under the curve dramatically — roughly a 64× improvement versus time/threshold GC schedules.
