C# web framework benchmarks: performance comparison

The fastest C# web framework in HttpArena is genhttp-ioxide, with a composite of 7006 on HTTP/1.1 — 1 of 72 against every language in its league. Measured over Alpha Round, every entry on the same machine.

Compare any two C# entries profile by profile →

Every C# entry in the benchmark, compared on the composite score of each family. The composite sums a normalized score over the profiles of that family, where the leader of each profile scores 100, and scales the sum by the entry's completeness factor. Rank overall is the entry's place in its own league across all languages; rank among C# narrows the same field to this language. Both link through to the board view they were taken in. How the score works.

Composite scores compare directly across every row. Ranks do not always share a field: a tuned entry has no place in the standard-only ranking, so its rank is taken from the field that includes tuned entries and counts more of them.
