# GraphQL Federation Benchmarks > Compare GraphQL federation router and gateway performance for Fusion, Apollo, Hive, Cosmo, Grafbase, Caliban, and feddi. See throughput, latency, memory and CPU usage, and hardware. Canonical source: https://chillicream.com/benchmarks/graphql-federation An open benchmark of GraphQL federation routers/gateways. Each router is evaluated under the same conditions, on the same machine with the same subgraphs and the same GraphQL operation, so you can compare throughput, latency, memory and CPU on equal terms. New results are published every day from a public workflow that anyone can inspect or rerun on their own hardware.

its cores are fully busy on both threads. | ReliabilityThe share of requests that passed the checks for HTTP status, GraphQL errors and response structure. | Run varianceHow much throughput varied across the measured runs, as the coefficient of variation. | | ------------------------------------------------------------------------------------- |

Every scenario runs these steps in order, one router at a time. 1. Start The router runs on 2 dedicated physical cores (4 hardware threads). CPU boost is disabled to reduce clock-speed variation. 2. Warm up One run of the full scenario length primes the router before anything is measured. Its results are discarded. 3. Measure 9 more runs of the same length follow. Each one sends the same GraphQL operation with the load profile of the scenario. 4. Check responses A request only counts as a success when it returns HTTP 200 without GraphQL errors. 5. Report the median Results use the median requests per second of the 9 runs, and run variance shows how much the runs differed. ### Hardware Processor AMD Ryzen 7 5700G with Radeon Graphics CPU topology 8 physical cores (16 hardware threads, SMT).
