Why Splitting a Task into 5 Subagents Can Be Slower Than a Single Agent

The article explains that parallelizing a task across five Claude Code subagents often yields no speedup—or even slowdown—because true parallel gains depend on independent task parts, while four overheads (re‑learning context, dependency chains, shared file conflicts, and single‑point aggregation) can dominate the runtime.
