Do large threads slow town the average forum speed?

At my forums there ar threads with more then 17000 posts.. Is it possible these threads are slowing the complete forums down?

I have about 170 users online now, only 3 of them are using the search function.
But my server loads vary from 1.20 - 3.20.. And the forums are extremely slow.

Well, I really dont know, but I've had discussions over this subject since I started using board software.

They shouldnt unless you're users are viewing that thread constantly or in large groups.

Either way it should still only retrieve the number of posts you have it set to display per page.

Currently Active Users Viewing This Thread: 46 (39 members and 7 guests)
==> that's for the 18.000 replies thread, 30 posts a page.

So imagine (it won't happen but say) al thse users where accessing a different page. That means 46*30 = 1380 posts requests out of the database.
That's a big number.. But propably most users are only browsing the last few pages of it.

Still.. My server loads are higher then I want them to have.

Take a look at your slow queries log and you'll get a better idea of what's causing the forum to take it's time. Out of the box vB uses the myisam table type which will lock the post and thread table while the thread is being generated so this will slow down all the other thread display requests that are pending.

Aha! That sounds interesting.

The answer is yes.

I limit all my threads to 1,000 posts (automatically split and linked). Reduced my load about 3 years ago when I started doing this by a lot.

Sounds great!

How do you limit threads to 1000 posts? Is that an option or a vB hack?

Option would be great! Aldough I have enough moderators, it would be nice if it would go automaticly.

Any luck with the code that "makes your forums seem faster" . Anyone try it? :rolleyes:

Exactly what it says it does, it SEEMS to make your forums faster.. When you're waiting about 5 seconds for a page to open that hack is useless.

Ok lets say your forums were faster..
