[Bug?]: big delay on a script (or command) execution

[Wroud]

Self-service

• I'd be willing to implement a fix

Describe the bug

Yarn delay for scripts is too big comparing to npm

macos:

wroud@wroud client % time yarn echo
ok
yarn echo  0.28s user 0.05s system 120% cpu 0.266 total
wroud@wroud client % time yarn echo
ok
yarn echo  0.28s user 0.04s system 130% cpu 0.243 total
wroud@wroud client % time npm run echo

> echo
> echo 'ok'

ok
npm run echo  0.09s user 0.03s system 83% cpu 0.141 total
wroud@wroud client % 

windows (powershell):

PS D:\work\personal\foundation> Measure-Command { yarn echo }


Milliseconds      : 434
TotalMilliseconds : 434.9869



PS D:\work\personal\foundation> Measure-Command { npm run echo }


Milliseconds      : 285
TotalMilliseconds : 285.7122

nesting:

"scripts": {
    "echo": "echo 'ok'",
    "echo2": "yarn echo",
}

wroud@wroud client % time yarn echo2
ok
yarn echo2  0.78s user 0.11s system 84% cpu 1.058 total

this is actual for any composite script like 'tsc -b && yarn bundle'

comparing to npm:

  "scripts": {
    "echo": "echo 'ok'",
    "echo2": "npm run echo",
  }

wroud@wroud client % time npm run echo2

> echo2
> npm run echo


> echo
> echo 'ok'

ok
npm run echo2  0.18s user 0.05s system 91% cpu 0.249 total

To reproduce

I use monorepo with pnp (but switching to node_modules have no effect)

script is "echo": "echo 'ok'",

Delay is really noticible. It also affects all comands not only scripts.
It's critical when runned in ci/cd or with combination 'yarn workspaces foreach`

here is an example: https://github.com/Wroud/foundation/actions/runs/12098355117/job/33734738575
you can see that "Release" and "Tag" steps took almost the same time

[@wroud/preconditions]: Process started
[@wroud/preconditions]: Tag already exists:  preconditions-v0.2.1
[@wroud/preconditions]: Time: 34
[@wroud/preconditions]: Process exited (exit code 0), completed in 1s 367ms

here you can see that script itself executed in 34ms when total time is 1367ms

when directly executed:

wroud@wroud di % time yarn ci git-tag --prefix di-v
Tag already exists:  di-v0.15.1
Time: 36
yarn ci git-tag --prefix di-v  0.88s user 0.12s system 128% cpu 0.771 total

Additional context

No response

also, yarn command take twice more actual time (delay + execution time)
