Description

When validating a form on a DoctrineMongoDB ODM Document with many Collection fields, the TypeContextFactory::createFromClassName() method is called several times to parse:

• ClassMetadata.php
• UnitOfWork.php
• PersistentCollection.php.

It uses PHPStan Property extractor to parse the docblocks. UnitOfWork and ClassMetadata docblocks are huge. This slows the form validation.

How to reproduce

Call:

for($i=0; $i < 20; $i++) {
$this->typeContextFactory->createFromClassName("Doctrine\ODM\MongoDB\PersistentCollection","Doctrine\ODM\MongoDB\PersistentCollection\PersistentCollectionTrait");
}

Possible Solution

Please add a cache to TypeContextFactory::createFromClassName() to limit resource usage due to running PHPStan property extractor on already parsed classes.

Additional Context

PHPStan Property extractor also has a resource issue when parsing type declarations with < (arrays, generics, collections). It always tries to determine if its an HTML tag, regardless of the type declaration context.
