Slowness since an upgrade

[epeliberty]

Bug report

Since we updated the version of PHPStan from 0.12.84 to 1.7.15, we have significant slowness in CI testing via Github Actions.

For the same file volumes we went from an average of 1min20 to more than 6min.

Code snippet that reproduces the problem

Before in our composer.json

"require-dev": {
        ...
        "phpstan/phpstan": "^0.12.19",
        "phpstan/phpstan-doctrine": "^0.12.10",
        "phpstan/phpstan-phpunit": "^0.12.8",
        "phpstan/phpstan-symfony": "^0.12.6",
        ...
}

After

"require-dev": {
        ...
        "phpstan/phpstan": "^1.7",
        "phpstan/phpstan-doctrine": "^1.3",
        "phpstan/phpstan-phpunit": "^1.1",
        "phpstan/phpstan-symfony": "^1.2",
        ...
}

In our Github Actions :

      - name: Run PHP STAN on whole project
        run: vendor/phpstan/phpstan/phpstan analyse --configuration=phpstan.ci.neon --error-format=prettyJson

Currently, it is difficult for us to have this slowdown of several extra minutes for each validation of pull requests :(

Do you have an idea of the origin of these slowdowns since the PHPStan upgrade?

We are still in PHP 7.4 for a Symfony 3.4 project

Thanks in advance

Not https://phpstan.org/try/... because it's during CI Validation

[mergeable]

This bug report is missing a link to reproduction at phpstan.org/try.

It will most likely be closed after manual review.

I suggest to follow the advise from #7581 (comment)
If you're lucky, people can optimise phpstan based on the profiles.

thanks @herndlm

There was no follow up information to act on. I suggest you try PHPStan 1.8.3 once it's released, and report back if the problem persists. Thanks.
