The situation
In a fictional dispatch library, adding more helpers does not shorten the queue: every independent task waits for the same key. The illustration asks where work must be coordinated and where it can proceed independently.
What the source supports
GitHub’s 21 October 2026 engineering article describes adapting its Git infrastructure for agent-scale workloads. It describes changing the scope of write ordering from the whole repository to individual references, so that writes to different references can be in flight at the same time. The post says each write still experiences the cross-region latency. Work on the same reference still requires coordination; independent references need not share every wait.
Practical questions
Our practical question is: what resource do these tasks share? Map the dependency before adding more agents. Separate independent work where the system supports it, retain ordering where writes can conflict, and measure the actual end-to-end result rather than counting assistants.
Limits and disclosure
The library, keys and workers are fictional analogies. GitHub describes its own architecture; this is not a benchmark or a promise that adding agents, parallelism or infrastructure changes will speed up another business. No performance figures or customer outcomes are claimed.
