This PR introduces an optimization to `set_response` to reduce the overhead for responses with a payload size less than 64 bytes. Performance gains are more noticeable when `is_request_compressible` enters the slow path, ie: `-H 'Accept-Encoding: unknown'` ### Benchmarks ```js Deno.serve({ port: 3000 }, () => new Response("hello")); ``` ``` wrk -d 10s --latency -H 'Accept-Encoding: slow' http://127.0.0.1:3000 ``` --- **main** ``` Running 10s test @ http://127.0.0.1:3000 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 44.72us 28.12us 3.10ms 97.95% Req/Sec 112.73k 8.25k 123.66k 91.09% 2264092 requests in 10.10s, 308.77MB read Requests/sec: 224187.08 Transfer/sec: 30.57MB ``` **this PR** ``` Running 10s test @ http://127.0.0.1:3000 2 threads and 10 connections Thread Stats Avg Stdev Max +/- Stdev Latency 42.91us 20.57us 2.04ms 97.36% Req/Sec 116.61k 7.95k 204.81k 88.56% 2330970 requests in 10.10s, 317.89MB read Requests/sec: 230806.32 Transfer/sec: 31.48MB ``` |
