rama

Flagship · Rust · engine: rama-http-core · standard configuration · completeness 4/4

Rama 0.4 on the multi-threaded Tokio runtime, default configuration. Routing and path/query/body extractors through the rama web Router, JSON via its Json response, compression through the rama CompressionLayer, static files through ServeDir, TLS via rustls and WebSocket via the rama-ws acceptor.

Composite rank

Each profile of a family is worth 100 to the entry that leads it, and the composite is the sum over the family, less 2.5% for each of routing, middleware, request and response the entry does not do for you - its completeness factor, which the WebSocket and gRPC families do not carry. The field is this entry's own league: engines and reverse proxies are scored apart from frameworks. How it works.

Family	Rank	Composite
HTTP/1.1	32 of 84	3174
HTTP/2	27 of 30	163
WebSocket	27 of 29	338

Alpha Round, 29 runs. Requests per second is the best of three; latency, CPU and memory come from that run.
