I generally dislike vBulletin with a passion because it is such a slug loading pages on a rural dial-up, which is my only option out here so far... Others have said that's just the way vBulletin is... However, this forum is noticeably FAST Questions: (1) what did you do to get it this way? (2) can you please contact all other vBulletin forums and explain how they can do it too?
I use some things to speed it up... The whole thing uses mod_gzip, so a 40k page is compressed down to about 7k (then uncompressed on the user's side), and I moved my CSS to an external file (vBulletin includes it on every page by default).
Well it works GuyFromChicago... are you reading this? I have seen it suggested elsewhere that using gzip (1) is a heavier load on servers and (2) may present some challenges to spiders... any truth to either of these as far as you know?
It most definitely is a heavier load on the server, since it has to compress everything that goes out on the fly. I wouldn't suggest turning it on unless you have some beefy dedicated servers (which I do). It's not an issue for spiders though... Most spiders use HTTP/1.0, which doesn't support gzip (so the server doesn't do it). Google is starting to deploy a HTTP/1.1 bot that does support compression though (there is a thread over here).
Store CSS Stylesheets as Files? If you would like to store the CSS stylesheet for each style as a file, you must ensure that you have a directory called 'vbulletin_css' inside the 'clientscript' folder, and that the web server has permission to write and delete files within that directory. thats what im referring to
It won't affect server load, and would probably speed things up a little bit since the CSS doesn't need to be reloaded every page.
