Hello is a simple HTTP server, responding with the string “world” to all requests. This benchmark is showing the peak requests per second, for an HTTP server running a single isolate.
File is an HTTP server that responds with the content of a 100KB file. This benchmark is mostly bound by file I/O.
JSON is an HTTP server that responds with the a dynamically generated JSON string, for each request. This benchmark reflects some REST-like APIs, where it’s common to JSON-encode the response.
Avg latency is the average latency recorded for all requests sent. For a single request, latency is the time passed from initiating the request to the full response has been received.
Max latency is the worst latency recorded, for all requests sent. While the average latency is closely bound to the requests per second, max latency indicates the HTTP server’s ability to schedule fairly under heavy load.
