FixBugs's team shows how token math, parallel chunking, and queues cut LLM agent latency: file analysis dropped from 10 minutes to 40 seconds.

The 2015 COST paper showed distributed systems often lose to a single thread. A worked case study reveals the real cost of premature scaling.

Drawing on Guara Cloud's build experience, this piece explains why 'pending' labels fail and how deployment status must be modeled as evidence-based distributed state.
