Installed Hacks - Forum slow?

[floridaideal]

Hi all

I have had more than 1 complaint about my forum being slow to load and post etc, it seems a lot of people are having this problem.

Early last week I installed the following hacks to my forum:

------------------Start Hacks------------------

PM Blink when full

Choose destination after post

Email admin when someone is trying to login in admin cp

Moderator drop down boxes

Quick fire reply + smiles

Spider Friend

Thread Preview (when you move your mouse over the subject of the thread you get a small box open with the first part of the thread)

Welcome Panel

Mouse over changes colour on forums

Also 'New Thread' link on index.php

------------------End Hacks------------------

Would any of these really slow down my forum? Most of them where template mods etc so I can't really see the damage!

Anyone ever had these problems?

Thanks

Stuart
