I think I noticed this starting a couple of weeks ago: a noticeable lag of a few minutes between the time I hit the "submit" button to the time my post, both new topics and replies, appears on the relevant board. At first I thought it might be an intermittent problem related to server performance or somesuch, but it now appears to happen on every single post. I was curious as to why this now happens. I assume it's intentional; if I were guessing, I'd speculate it's related to some security issue, fighting board spammers, etc. I just wondered what the rationale was.
