Agent speeds up a JSON scanner 1.7-2.1x on late-field lookups with a short-string fast path
arthurcolle · x · 2026-09-06
A user asked the Astra agent to speed up code without errors. The original JSON scanner walked long tool results and response text byte by byte; the optimized path is 1.7–2.1x faster for late-field lookups and 1.35–1.69x faster on 4–64 KiB response fixtures, with a short-string fast path avoiding a regression from the first attempt. Benchmarks are local CPU only, not model-latency claims.
