Which is the fastest GraphQL?

It's all about GraphQL server benchmarking across many languages.

Benchmarks cover maximum throughput and normal use latency. For a more detailed description of the methodology used, the how, and the why see the bottom of this page.

Methodology

Performance of a framework includes latency and maximum number of requests that can be handled in a span of time. The assumption is that users of a framework will choose to run at somewhat less that fully loaded. Running fully loaded would leave no room for a spike in usage. With that in mind, the maximum number of requests per second will serve as the upper limit for a framework.

Latency tends to vary significantly not only radomly but according to the load. A typical latency versus throughput curve starts at some low-load value and stays fairly flat in the normal load region until some inflection point. At the inflection point until the maximum throughput the latency increases.

These benchmarks show the normal-load latency as that is what most users will see when using a service. Most deployments do not run at near maximum throughput but try to stay in the normal-load are but are prepared for spike in usage. To accomdate slower frameworks a value of 1000 request per second is used for determing the median latency. The assumption is that a rate of 1000 request per second falls in the normal range for most if not all frameworks tested.

The perfer benchmarking tool is used for these reasons:

• A rate can be specified for latency determination.
• JSON output makes parsing output easier.
• Fewer threads are needed by perfer leaving more for the application being benchmarked.
• perfer is faster than wrk albeit only slightly
