We have #2525 and #6967 that are probably duplicates.

There was a lot of performance improvement since 2.9.6 among them #5587, #4814 or #4565.

Could you try upgrading and see if the performance became acceptable ?

[leandrogmuller]

Trying again.
pylint 2.14.3
astroid 2.11.6
Python 3.9.6

The same problem.
