It depends on the topic, but times are a little too long. Forum reports, easy to handle, are usually processed within 24hours. A connection request took around 5 days for me, with the easy response.
But as I said before, it depends on the problem. It seems that they're not really responding to certain bugs, such as the timer issues. Yes, they help some on this forum, but requests hardly pass. I think they do this because one general fix should help everybody, leaving more room to process other requests.
