Swarms said on September 30, 2026 that Swarms Rust, its Rust implementation of a multi-agent orchestration framework, beat LangChain, LangGraph and CrewAI by wide margins in a same-model, same-prompt, same-task benchmark. The company reported 130x to 440x faster startup, 25x to 68x lower memory usage, and 10x to 88x less framework overhead per LLM call.

A Rust Agent Stack Makes a Speed Claim

Swarms says its Rust framework starts far faster, uses less memory, and adds less per-call overhead than LangChain, LangGraph and CrewAI in a same-task benchmark.

130x-440x

Reported faster startup

25x-68x

Reported lower memory use

10x-88x

Reported less framework overhead

Maximum Reported Multipliers

Each stacked block represents about 10x; labels show the reported maximum for each metric.

440x

Startup

88x

Overhead

68x

Memory

What the Benchmark Is Testing

Inputs

Same model, prompts and tasks

Metric

Framework cost around LLM calls

Use Case

Cold starts and memory-limited services

Positive Read

The gains point to lower startup friction for serverless agents, evaluation sweeps and high-volume orchestration.

Critical Read

The headline is ratio-based, so raw timings and independent replication matter before production teams switch stacks.
