Why does it take so long for posts to show up here?

Just now am I able to see this thread since I posted the first post yesterday.

This has always happened for me here. It usually takes 1 day or so for me to be able to see new posts.

For example if I see a thread just started I wont see any messages added for like 12-24 hours. Then when it finally shows up it will be like 10 pages long lol so obviously other coud see it.

I think it had something to do with the cookie as when I deleted all cookies then new posts showed up.

No one else ever had this issue?
