Bigger graphs, bigger gains: GraphWorkflow beats LangGraph across 15 configurations
KyeGomezB · x · 2026-09-08
Swargs benchmarked GraphWorkflow against LangGraph across 15 configurations, from small workflows to 200-node chains, finding orchestration overhead grows with graph size — and so does the speedup:
- 7.0x geometric-mean speedup
- 62.5x faster on 200-node chains
- 21.6x–31.3x faster compilation
- 7.9x faster cold build→compile→execute path
The core idea is "compile once, execute many times": build an optimized execution plan up front instead of repeatedly paying graph construction costs, keeping large agent graphs practical in production.
