This commit changes "eager ops" to directly return a response value instead of calling "opresponse" callback in JavaScript. This saves one boundary crossing and has a fantastic impact on the "async_ops.js" benchmark: ``` v1.32.4 $ deno run cli/bench/async_ops.js time 329 ms rate 3039513 time 322 ms rate 3105590 time 307 ms rate 3257328 time 301 ms rate 3322259 time 303 ms rate 3300330 time 306 ms rate 3267973 time 300 ms rate 3333333 time 301 ms rate 3322259 time 301 ms rate 3322259 time 301 ms rate 3322259 time 302 ms rate 3311258 time 301 ms rate 3322259 time 302 ms rate 3311258 time 302 ms rate 3311258 time 303 ms rate 3300330 ``` ``` this branch $ ./target/release/deno run -A cli/bench/async_ops.js time 257 ms rate 3891050 time 248 ms rate 4032258 time 251 ms rate 3984063 time 246 ms rate 4065040 time 238 ms rate 4201680 time 227 ms rate 4405286 time 228 ms rate 4385964 time 229 ms rate 4366812 time 228 ms rate 4385964 time 226 ms rate 4424778 time 226 ms rate 4424778 time 227 ms rate 4405286 time 228 ms rate 4385964 time 227 ms rate 4405286 time 228 ms rate 4385964 time 227 ms rate 4405286 time 229 ms rate 4366812 time 228 ms rate 4385964 ``` Prerequisite for https://github.com/denoland/deno/pull/18652
