When Does A Thread Have Too Many Posts?

I have a welcome thread on my site that is 82 pages long. Does a thread that large put strain on the site? At some point should I close the thread and open a new one? My threads are set at 20 posts per page. Is that default btw?

 

I wouldn't imagine it would impact your site too much and if memory recalls yes 20 posts per page is default. Or around that mark.

 

Maybe this thread gives you some ideas of the possible problems with too long threads http://xenforo.com/community/threads/how-do-you-deal-with-very-long-threads.46108/

The Random Thoughts thread on my site is 532 pages long.
