Those queries, esp if you don't run the indexes, cause large if not full table scans...

So its going to read the entire thread and post tables... before it finishes.

nice, I'd love to have some of the largest tables in the database fully scanned on every page! lol

Installed =) Thanks!

Alright so I've installed it and I've got it set it to show on all pages. Gimme worst case scenerio as to what might happen by doing this? Would it just be longer page loads?

As your board gets bigger (more posts/threads) page load will increase. Once you board reaches a few hundred thousand posts/threads or even worse in the millions I woud fear being a member of your site.

Currently my board has: Threads: 17,869, Posts: 182,735 and I've noticed no drag on performance...

Zachery, please tell us why you recomend against it and the longterm effects of not doing as you suggested.

If you index dateline in your post & thread tables this hack will have a negligable effect, even if run on every page, that's what indexes are for. ;)

So just putting it on the forumhome_start will prevent this issue from happening?

Well it's defaulted to that hook when you install the plugin. Thus, forumhome is the only page that runs the php code to get the post count. As Paul and Zach stated, if you added the indexes it will help alot. I wouldn't recommend running it on every page if you have millions of posts or don't use indexes.

Please keep in mind, I'm not a php/mysql guru, however I do know a lil bit.

Is it normal to not update very often?

My vBulletin shows that no new message have been posted if you go by the generic image which is on the left side of the forum, but the mod still says "There has been 3 new posts and 0 new threads since your last visit."

Even when I refresh the page it did not change. It does update as far as increasing... I added a test post and it now says there are 4 new posts but the default vbulletin software shows that I have already viewed them.

The only way that I can get the counter to reset is to actually log out of the message board and then back in.
