Similar problem occurs when we start the SF itself, if freezes about 15 seconds before we can chosse an option.

The extender should not influence this behavior. 17 seconds is still way too long. Can you run the attached query on your SF database and let us know the results? The query is an improvement of the hotfix that might just do the trick.
If this does not resolve the problem, it would be a good idea to create a ticket with the SF database attached so we can reproduce and investigate the scenario further.
