I think the mods. I can't remember what mods I've been installed.
I only mark some mods, but still forget and too lazy to give "mark" another mods.
Too many custom code (outside PunBB), I grab it from here and outside there.
Just like everybody and Rickard said.. PunBB is easiest to understand, even with "stupid" newbie moders (not coder) like me 
Or, I think PunBB 1.2x has indexing search feature that double the size of post Database?
Last time, I delete or I didnt build index (at admin pages) 
The power and one of my visitor like is Search feature. I am using Search show_new, show_recent and show_24h mods.. That why, my visitor like. They wont go all forum or categories to find what is new post for today. 
Next month (May 2008) is a year I am using PunBB.
Before that, I am using Yabb, and move to SMF and using it for more 2 years. I like it.
With default install and theme's of SMF (I like Simplicity Themes by Bloc), causing high load resources.. Maybe my hosting provider had bad CPU performance not SMF. Well? 
3 times, I move from one hosting to another. They complain about my forum resources. One of them suspend my site without reason 
Can you imagine? I've got headache to download, upload and dump MySQL data every few month!
Last time, I've upload 150MB data one-by-one because internet connection too slow, at that time, the standar old PHPMyAdmin cannot hold few megabytes uploading data. I must copy paste manually into query box.
Yes, I know about dump program. Some hosting doesn't allowed that, I've been warning before.
Until... yes.. Until I found PunBB. Even not too many support community like SMF had, I like how the code wrote. Thanks to Rickard and The Team 
Finally, with PunBB 1.3 Beta with the extension (mod) WITHOUT TOUCH the core code? Its brillians idea.. Thats why, directly I am moving into Beta. I know the risk for my Production Forum.. But, If I stick with PunBB 1.2x, forever I will forget many "injected" code/mods. I can't make my forum growing with more advantages.. 
Thats Why, I take the risk..
