Description

As reported on previous Laravel versions, the laravel Validator is very very slow with large datasets:

• Validating large arrays are too slow ideas#2212
• [7.x] Performance improvements #32532
• https://stackoverflow.com/questions/71939857/laravel-validation-large-json-too-slow
• https://stackoverflow.com/questions/67316079/laravel-validation-timesout-for-huge-data
• https://laracasts.com/discuss/channels/requests/request-rules-validation-is-very-slow

I have tried to understand and review the validation process, but it is too complex to be able to send a PR. I could only find that it iterates thousands of times over all values when calculating the validation rules. The problem seems to come only when using asterisks in the fields to validate.

Here a tweet with some tests: https://twitter.com/lito_ordes/status/1735082009666494594
