Unified testing shows that Campfire's Rust version has approximately twice the throughput of the Go version; the early claim of 150 times has been questioned
DHH had AI port Campfire to Rust, Go, and Elixir; in unified testing, the Rust version achieved approximately 106000 requests per second, while the Go version achieved approximately 53000. The early performance gap was questioned because the degree of optimization and the architectures differed.
