Most of the questions will get a response within 24 hours. Complicated questions can take a little longer, and during the weekends the response time can be a little bit longer as well.

To speed up the process, please provide a clear description of your issue or make a video/screencast of the problem. Also, sending a temporarily(!) WP admin login will help to debug your issues faster.
Oh.. and you don’t get a faster response if you send multiple requests/emails/comments
