I've just posted a topic complaining about slow judge, and it received 4 downvotes in just 5 minutes, so I have no choice but to delete it. So could someone tell me is it normal that a submission need to wating for over 10 minutes to be judged?

Update: Now my new submission 191736305 has got AC, but it also has waited for 6 minutes.

Update; Encounter a problem on CF ---> post a blog for asking for it ---> get downvoted by unknown reason ---> be forced to delete the blog to save contribution ---> encounter more problems. How can this vicious cycle be stopped? The greatest disadvantage of CF downvoting system: I will never know the reason I being downvoted.
