We switched from lvl5 to 6 and generated baseline ~1mb (yeah, there are lots of things with no type hints). CI task running phpstan grew from 5 mins to 12+. As far as I see, that 5 mins added are spent not on analyzing, but rather on processing analysis results. So progress bar is filled up within 6 minutes, and then 5+ minutes is (I assume) spent doing results processing.

Is there any way to speed up errors processing? Looking through https://github.com/phpstan/phpstan-src/blob/a2c04036578f9a7d03c28a7e0414749c96724ec2/src/Analyser/IgnoredError.php#L54 I guess that the main impact is in the \Nette\Utils\Strings::match() call, that sets errors handler and removes it each call. Is it really needed?
