Keyhan Vakil 7eafd2f7e8 child_process: improve spawn performance on Linux ... Speed up child_process.spawn by enabling the new V8 build flag which makes fork/exec faster. Here are the results of running the existing benchmark. Note that this optimization helps more for applications with larger heaps, so this is somewhat of an underestimate of the real world performance benefits. ```console $ ./node benchmark/compare.js --runs 15 \ --new ./node \ --old ~/node-v20/out/Release/node \ --filter params child_process > cpr $ node-benchmark-compare cpr confidence improvement (***) methodName='exec' n=1000 *** 60.84 % ±5.43% methodName='execFile' n=1000 *** 53.72 % ±3.33% methodName='execFileSync' n=1000 *** 9.10 % ±0.84% methodName='execSync' n=1000 *** 10.44 % ±0.97% methodName='spawn' n=1000 *** 53.10 % ±2.90% methodName='spawnSync' n=1000 *** 8.64 % ±1.22% 0.01 false positives, when considering a 0.1% risk acceptance (***) ``` Fixes: https://github.com/nodejs/node/issues/25382 Fixes: https://github.com/nodejs/node/issues/14917 Refs: https://github.com/nodejs/performance/issues/93 Refs: https://github.com/nodejs/performance/issues/89 PR-URL: https://github.com/nodejs/node/pull/48523 Refs: 1a782f6543 Reviewed-By: Yagiz Nizipli <yagiz@nizipli.com> Reviewed-By: Juan José Arboleda <soyjuanarbol@gmail.com> Reviewed-By: Debadree Chatterjee <debadree333@gmail.com>		2023-06-24 17:34:44 +00:00
